Every child in England will soon be having lessons at school about growing up and relationships.
Not everyone's happy about it as some people think it should be up to your mums and dads to teach you the facts of life, but what do you think?
Do you already have lessons like this? Do you think they're a good idea?
Maybe you find it too embarrassing to talk to your mum and dad about growing up? Would you prefer to find out at the same time as your mates? Or is it the other way round?

"I do not want to hear about it at school. Your parents should tell you all about it."
Cathy-Ann, 11, Belfast, Northern Ireland
"I would feel better learning about it at school as it will be less embarrassing because everyone else is learning about it, too."
Harriet, 11, Stockport, England
"I'm 13 and I've personally had more lessons then I need, but every kid needs them because I would find it embarrassing to talk to my mum about it."
Louise, 13, Bedfordshire, England
"I think that it is a good idea because people will know what to do if they find themselves in an uncomfortable position, and a lot less teenagers will get pregnant in the UK."
Katy, 10, Adelaide, Australia
"I think it is a good idea because you will have to know sooner or later. I think it would be better sooner to be honest with you!"
Amelia, 10, West Sussex, England
"I thought it was funny at first but they are taking it too far now. Someone fainted in our class after watching a video."
Adam, 12, Solihull, England
"I don't mind it; to me it sounds like a good idea to teach it at schools."
Chloe, 12, Milton Keynes, England
"I think it's a very good idea as children need to know about the future."
Sam, 12, Shropshire, England
"I just think it's revolting when we're in class and the teacher is talking about bodies and relationships."
Chloe, 12, Southend, England
"At my school I think we have enough lessons about body and relationships. I think it's the pupils that get embarrassed, rather than the teachers."
Hollie, 12, Surrey, England
"I don't think it's a good idea because younger children might get into serious relationships."
Jasmin, 10, Co Tyrone, Northern Ireland
"I find it really disgusting to have body lessons at school and I really don't want to know about it."
Jane, 13, Glasgow, Scotland
"I think it's good because it's about growing up and if you'd never had it you might be in trouble when you get older."
Stephen, 13, St Helens, England
"I don't mind being taught about it at school. It's not as awkward as being told by your mum or dad, and you get to have a giggle with all your mates as well!"
Holly, 12, Brighton, England
"As a 15-year-old I've had more than my fair share of these kinds of lessons and for me they've never been embarrassing. I don't mind being taught them at school because you're with your friends, and you can have a laugh. My parents don't talk to me about it so I was grateful for school."
Eleanor, 15, South East Wales
"I think we should learn it in 5/6, and girls separate from boys, so everyone feels comfortable talking together."
Krishma, 11, London, England
"I think they should have rules because they might be teaching you the wrong thing."
Priyanka, 11, London, Britain
"I believe it is important for children in secondary school to be taught the facts of growing up by teachers and parents, as it will be needed for our future lives."
Lauren, 13, Edinburgh, Scotland
"I think that they should treat us like adults so we can learn about it."
Izzie, 10, East Riding of Yorkshire, England
"I don't mind being taught this at school. I disagree about parents not allowing schools to tell their children about this, as some parents are embarrassed and the children would not find out some important information."
Meghan, 11, Belfast, Northern Ireland
"I think it's a bad idea."
Charlie, 13, Sussex, England
"I think it is good that we get to learn about it because our parents might not be able to explain."
Samina, 13, London, England
"I think that lessons like these should not start until secondary school, because children under nine don't really understand what the teachers are talking about."
"Because I go to a girls' school I don't feel embarrassed to talk about it. I think everybody should be able to have lessons on it."
Lili, 12, London, England
"I think our parents should tell us, not our teachers."
Sean, 11, Buckinghamshire, England
"I do agree with the government, in the sense that we should be taught about our body, but not at five! I mean, five-year-olds don't need to know about this stuff. They should be playing with their Barbie dolls, not worrying about what will happen when they are 10 years older."
Lizzie, 12, England
"I got told about it first in year six. Now I'm in year nine they haven't stopped talking about it. We even had to watch a one-hour long play on building relationships."
Louise, 12, Lancaster, England
"I think it should be your teachers that tell you about changes about growing up, because my mum and dad found it hard to talk to me about it."
Kirsten, 11, Glasgow, Scotland
"I think it is a bit gross but you have to learn it sometime, sooner rather than later I think."
Emma, 11, Worcestershire, England
"We got zilch about growing up in primary. Then when we got to secondary we had biology lessons and also P.S.E. telling us. I think kids should start learning when they are in their last two years in primary school."
Becky, 13, Glasgow, Scotland
"I go to an all-girls school and it is better to learn about it at school that way because my mum gets very embarrassed about it and just clams up and so she is not very good to talk to."
Rachel, 12, West Sussex, England
"I think it's a good idea to start at the end of year five. I would choose to do it in class rather than with my mum/dad because they will have been through it but... it's just different with parents - you don't want to say anything, but in class you can say nearly anything. So I think it's a good idea. And you would be so embarrassed to tell your parents but with your mates, they understand you more (in this, anyway) because they are going to go through it about the same time as you. Boys learn it with men teachers and girls with woman teachers. They start in year five - perfect timing!!"
Tia, 11, England
"I think that children at five shouldn't be told about things like that. I think that it should be some thing like eight-year-olds rather than five-year-olds but it is good to let more people know because some parents might not tell their children and we have a right to know because it is really important."
Emily, 11, Preston, England
"I think that children should get taught about relationships but not at the age of five years old as it is too young for them to understand. Yes, I think that talking about it with your mum is a bit embarrassing."
Alice, 12, Nottinghamshire, England
"I've already learnt about everything and I think it is a good idea but the parents should have a say in this and I think five is a bit young because they will not understand anything. But if the children are too old they will just laugh. So I think it should be up to the parents and not the government."
Danielle, 12, Wales
"My old primary got the school nurse to talk about it to us in years five and six. I think it is a good idea to teach years three and four but I think it is ridiculous to teach children when they are five!"
Georgia, 11, Slough, England
"I have no problem with learning about growing and changing. It's all perfectly natural and you don't want to grow up confused."
Amy, 11, Scotland
"I think that our lessons at the moment are limited and that we should be taught more about growing up as it is essential for later on in life."
Freya, 10, London, England
"The nurse talked to me about it when I was in Primary 6 and all the other girls kept on giggling. I'll be getting it again this year but the boys and girls will be together making it even worse..."
Shauna, 10, East Kilbride, Scotland
"I think that lessons on growing up are a ridiculous idea! If parents thought that they needed to find out more about it then they could take a book out from the library - I did and it told me everything I needed to know."
Thomas, 10, Liverpool, England
"I think having these lessons at school is a great idea, it will encourage young kids to make the right decisions in life and will give them more confidence."
Nada, 12, Manchester, England
"I think body and relationships are very personal subjects and should be taught by a parent or carer."
Hannah, 11, Liverpool, England
"I think it is easier to talk to teachers or counsellors about body and relationship lessons than my parents because I think it is embarrassing. School is for education so they should teach things like this."
Alison, 13, Wales
"I think that it is really good that you have lessons about your body changing but I would rather talk to my mum than talk about it in class."
Shannon, 11, Newcastle, England
"It's all right, I suppose, but it's too embarrassing to discuss with mum or dad!"
Tasha, 11, Leicester, England
"I think it's great! Many kids are worried about all that stuff, including me. If we learnt more we would feel more comfortable and be able to enjoy changing!"
Kim, 12, Sussex, England
"I think it's really embarrassing talking about the changes that your body takes in school because all the boys laugh at you and keep going on about it. You'll need to know about it at some stage, but relationships are fine to talk about!"
Hannah, 13, Northern Ireland
"I don't think that we should have relationship lessons until we are in year five. When you are 10 you can take stuff seriously. I think starting at the age of five is way too young and is completely pointless!"
Lucy, 11, Gloucester, England
"If my school was going to get those kind of lessons I think it would be strange because they would say all these things that might happen to you and it might make you worried about the future and what you would look like."
Anastasia, 10, Scotland
"I find it embarrassing at school - unless it's just with mates."
Anna, 12, Kent, England
"We were meant to start in year five (I'm now in year eight) but we only had one lesson. We did a little bit in science last year, but that didn't cover anything personal. Last year, we were meant to talk about it in tutorial lesson but we never did."
Erin, 12, Huddersfield, England
"Some kids in year eight at my school had a special assembly about growing up. I'll probably get that next year."
Georgina, 11, London, England
"I think that pupils should be taught about how their body changes when they are young because I think it is very important. But if parents don't want their kids to be taught at school they should be allowed to miss the lessons."
Bruce, 14, Edinburgh, Scotland
"We had these lessons just before we came to high school. It was OK but I don't think they should give it to children at a very young age."
"I think that five is too young to be learning about this stuff - I think you should learn it from age 11+."
Chloe, 12, England
"I think it's really important for us to learn stuff like this, but I think that the BOYS might act a little inappropriately."
Kate, 12, London, England
"I think they should start it in year five, but any younger is silly. Kids should be allowed to be kids and not worry about that stuff."
Katie, 14, Wirral, England
"I think it's a good idea. It is very embarrassing talking about it in school, but it is better than asking your mum and getting all shy. We wouldn't get shy if we had learnt it because we would have already talked about it."
Elisha, 13, London, England
"I don't think we get taught enough at school on growing up, and I think we need to know when we get to secondary school because we might not know what is going on around our body. I think it is sometimes more embarrassing for your parents to talk to you about it than your teachers. "
Cymi, 12, Southampton, England
"I hated it!!!!! I wish I never had it and I think it was sooo annoying that the teachers sent you to the head if you laughed."
Leah, 12, Aberdeen, Scotland
"I think it is a little bit embarrassing. However, it's part of growing up!!"
Rebecca, 11, Manchester, England
"It is absolutely necessary for these lessons to happen at school. Luckily I had some lessons about all this, but many of us are not getting taught enough about this subject. From five years old you should be taught about relationships, as in friendships, and this sort of education should progress up to when you leave school. Also, I cannot stress enough how important it is, when learning about relationships, for kids to be taught equally about same-sex relationships. All these things need to be part of the curriculum and must be taught, regardless of whether the school is religious or not. School should prepare us for the real world."
Poppie, 14, Kent, England
"If you start when you're five, it's not that bad, because you just register it as normal... But if you suddenly start when you're 13, it would be SO embarrassing. I go to a mixed school and LOADS of girls want to ask questions, but because of the boys, it's embarrassing!"
"We already have lessons like this and they're not really that bad! They are actually quite interesting!!"
Lucy, 14, Buckinghamshire, England
"I think it's OK. But I think we should be taught more about respecting our bodies."
Poppy, 13, Kent, England
"I think it's a brilliant idea as it will help us in the future."
Josh, 12, Devon, England
"I think you should. I had some in year four and it was good to get taught then."
Lewis, 9, Dorset, England
"We have lessons like this at school and they should do it at every school!"
Zoe, 13, Surrey, England
"I started learning about this sort of thing in school when I was about nine. But to be honest, I already knew most of it at about seven. But I think it's wrong to teach these things at such a young age. Leave it to the parents!"
Aliyah, 13, England
"To be honest, I don't think that we get taught enough about our body and growing up."
Nic, 13, Sheffield, England
"I think that making it the law to have more lessons about relationships is a good idea because then we will know more and be able to keep ourselves safe!"
Maddie, 12, Norfolk, England
"A good idea. I have a male teacher and it is still OK, but a bit embarrassing, though."
Rachel, 12, London, England
"I found it quite embarrassing, really. My Mum had already told me 'the facts of life' before we covered it in year six. The girls and boys were split up, though, so that was good. When we covered it in year seven, boys and girls were all together and nobody said anything because they were all too embarrassed..."
Louise, 12, Lancaster, England
"It's fine to learn about it, but they should split up boys and girls because otherwise it's totally embarrassing!!"
Eden, 11, Kent, England
"I think it is a good thing because some parents don't like telling their children about growing up or vice versa. In my school, we started learning about it in year five. People are embarrassed to talk about it, but it is a thing we all need to know."
Georgia, 12, Cardiff, England
"I don't think there is anything wrong with learning about it because if we didn't we wouldn't be aware of the dangers when we get older."
Aoife, 12, Ireland
"I think it's a bit weird when your teacher talks about growing up and changes in your body, but talking to friends and discussing it seems a bit more relaxing to me!"
Angel, 12, Manchester, England
"Everyone in my class talks about these things all the time. In my opinion, it is perfectly normal to talk about it."
Mathew, 13, Manchester, England
"We did the girls' side of life in primary school, and so did the boys, but we were separated so no-one got too embarrassed. Then in first year of secondary we went into more detail in biology and everyone just stared at their books because it was so embarrassing!"
Catherine, 13, Belfast, Northern Ireland
"I totally agree with having relationship lessons; it's all fine being taught the biological facts, but the relationship side is a lot harder to cope with. This is a good idea, and the parents who think it isn't are too shielding of their children."
Lucy, 15, Middlesbrough, England
"I do not think little children should know what happens when they grow up at such a young age, because they might get scared."
Bethany, 10, Kent, England
"I think it's a good idea, but not for little kids as they might not understand."
Joshua, 10, Swansea, Wales
"I agree with the government; my school didn't tell me much, but my secondary school did. Children should be brought into it slowly so it doesn't come as one big shock!!"
Emily, 11, Kent, England
"I think we should know so it helps us to be careful."
Daniel, 12, Middlesex, England
"I think schools should tell you about growing up earlier than they do. They leave it a bit late!!!"
Caddy, 11, Newport, Wales
"I have had lessons like this from when I was 10 in primary school."
Irrum, 12, Manchester, England
"I think that it is good to talk about growing up for boys and girls because we know when we are changing and why!"
Eleanor, 10, Bury, England
"I've already learnt about it in Year 5. It's OK, because the girls learn it in one classroom, and the boys in the other. I'm so glad we're not together, it's so embarrassing!"
Lina, 10, London, England
"I think that we are growing up so we should learn more about this subject, and they should treat us like adults during that lesson."
Erin, 10, Norwich, England
"I think that it is really good that children are being taught things that they will need to know in later life. It may be embarrassing, but I feel very strongly that it is the correct thing to do."
Deadre, 12, Newcastle, England
"I feel embarrassed, especially when we learn these things in the same room as the boys."
Katrina, 13, London, England
"I think that children are growing up too quickly. Where did the "innocence of childhood" go? Learning about this teenage topic at the age of 5? The government must be joking!!!"
Millie, 13, London, England
"I think it's a good thing for children to learn about that kind of thing. But lots of people just laugh at it and don't take it seriously, even when they get older, so the teachers don't bother teaching it."
Emma, 12, Edinburgh, Scotland
"I personally think that it is not the job of a teacher, parents should decide when they want their child to know."
Emma, 12, Blackpool, England
"I think it is a great idea. There are people my age that don't have a clue about anything and when they go to high school they might get picked on for not knowing."
Jennifer, 12, Northumberland, England
"I think this is a good idea and I see nothing wrong about it; but the only thing that puts me off is that at primary school when you learn about the facts of life the teachers are really uneasy about it, which makes you wish you never had the lesson."
Alice, 11, Trafford, England
"Well someone has to explain to us don't they?? It may be embarrassing to some, but it's going to happen to every child so we might as well all know about it!"
Kirsty, 12, Watford, England
"I think it's absolutely disgusting when they tell us that, because we're too young to learn about all of that. Everyone bursts into laughter because people our age don't really take it seriously."
Penelope, 11, Cardiff, Wales
"I think it is suitable for people over 10, because there are bits of your body that you don't like talking about."
Felicity, 10, Bromley, England
"I had it in Year 6 and thought it was good to be around your friends!!!"
Julia, 11, Leicestershire, England
"I would rather have talks at school than with my mum."
Rebecca, 13, Kent, England
"I don't mind it. But all the boys laugh all the time and it's very annoying."
Siobhan, 12, Kent, England
"I thinks it's good to know about your body and relationships because some people begin to develop at a young age and it's good to know what happens, so you don't worry too much."
Lauren, 14, West Sussex, England
"I think teaching kids about the body and relationships is a good thing. It saves the embarrassment of your mum telling you. You can just laugh it off with your friends if you learn about it at school."
Bethan, 14, Gloucester, England
"I think it's embarrassing talking about it in school, but at the end of the day you will need to know it."
Gurprit, 12, Birmingham, England
"We already had a lesson on it but I didn't want to get involved. I was called names because I didn't want to get involved and it was almost bullying."
Amelia, 10, Dudley, England
"Only the Year 7 girls in our school have been talked to."
Scott, 10, East Kilbride, Scotland
"Its OK but I haven't started it that much at the moment and I'm in Year 7."
Hannah, 11, Yeovil, England
"I think it's normal and I'm in Year 7 and I had these lessons in Year 5. Most of my class laughed but I didn't. Me and my buddies talk about growing up all the time and I am quite excited about it!"
Helena, 11, London, England
"I'm glad we are getting lessons, it's so embarrassing to talk to your parents!"
Alice, 14, UK
"We were taught the facts of life at the age of 9-10. I thought that was a bit early but a girl in my class started to develop before she actually knew about growing up so I guess it's a pretty good time to start learning. I suppose it is a good idea to have lessons at school, even if it is a bit embarrassing."
Alice, 13, Cambridge, England
"I find it really embarrassing talking about it at school, but things like relationships are better than about your body. But I'd rather talk about it with my mum!"
Emma, 11, Caithness, Scotland
