I think there's a massive double standard on women with this being "mature" enough to have sex idea. Why is it that when a male gets to his early teens and his hormones come rushing in he can just go yes, this feels good, do want. and explore his developing sexuality. And when a girl reaches her early teens, and she's horny as fuck too everything is new and exciting and she wants to go yes, this feels good, do want she CANT because she is bombarded with silly ideas from society that tell her she is supposed to want to save it for some mythical magic moment, and its supposed to be perfect and if she were to go with her feelings and express them she is told she will later look back and regret it. WTF Boys express their sexuality as comes naturally and we are conditioned to repress ours with a mounting sexual anxiety over expectations that everything has to be perfect first time, and on top of that the so-called moral implications of being human and having normal human appetites, which apparently makes you a slut. If a boy goes out on a date and the girl puts out she is a "slut" The boy having done the exact same thing goes without any mention of moral judgements on his behaviour and may even himself reguard the girl as dirty or slutty irrespective of the fact they have both engaged the exact same act. I think that exploring your sexuality as it develops is desirable for both sexes, as long as if any experimenting with others coming into play is practised safely with peers who are also consenting. (obviously not someone who would exploit their sexual naivety beyond its nature rate of development for their own gains ).
Bit of a rant, but sexuality is not something to feel you have to be ashamed of simply for the crime of being female.
What girls(and boys) should be taught imo is the self confidence to explore sexuality at their own pace and not to allow anyone to push them into something they don't want and equally not to allow ridiculous hypocritical double standards to hold them back with fear or shame which may arrest their sexual development.
Sorry, but raised by strict religious parents taught me I was evil if I felt attraction to anyone before I'd finished school and gotten married, that if I touched my own body or even thought sexual thoughts Jesus was there, listening and judging, and condemning me to eternal hellfire. It was stressful and I am angry about it. The next generation needs to be free.
