I've had sex at 15 the first time.It was great, it was also strange.
It's not like you imagine it.Anyway I think that when's you're attracted from another girls, and she's attracted too, there's nothing wrong into doing sex, whenever there's respect you can do anything.But sometimes, teen agers thinks having sex is like a game or thinks they "MUST" have sex in their early years, like they are playing a competition and that's wrong.
Sex is good when it's something that give you pleasure and is not sawed as a game or a something you "MUST" do.I've had sex most of the times cause I wasn't even looking for a girl that want it, than the times I was thinking I "NEED" it.
