Again, no. Its probably because you haven't had a growth spurt yet, which means when everyone else already had theirs, you start growing. Thats something I heard (my mom is a paramedic) so Idk if you'll do it but theres a chance.
When I told my mother I thought I was Dirty Minded, she said that I wasn't. She simply said It was because I would be going into Puberty. She said it was normal to think about those stuff since In the future I'd be doing them. I'm guessing its the same for you.
