You can limit opportunities, but all you will succeed in doing is making the child more devious.
Oh what a load of shit. You can make your child more resentful, and that's fine. But you most certainly can stop your child from going out anywhere without strict supervision. You're the parent, not a friend. If your 12-14 year old child is continuously having sex, you've fucked it up as a parent. You can limit opportunities. You may not have a 100% success rate, but to not try is unfathomable. I agree with what, you do come down like a ton of bricks. Part of parenting is saving your child from themselves.
Personally even at 17, while my child is living at home I'll be limiting opportunities. She certainly won't be having sex under my roof and her boyfriend won't be spending the night. She can do it elsewhere. When she's a legal adult, the rules will change and hopefully by that time she'll have enough maturity to understand what a healthy relationship is.
And all this talk of exploitation, not valuing herself etc.has it not occurred to you that they are having sex for the same reason we do- because they are horny for one another.
You mean "we" as in the adults posting on this forum? The adults that have the emotional and mental maturity to be able to deal with the emotional and physical aspects of a healthy relationship? Surely you're not comparing a 12 year old or even a 14 year old for that matter to an adult. A 12 year old does not understand the full implications of what she's doing. She can rote memorize a sex ed book all she wants, she doesn't have the emotional maturity to understand the full implications, and she doesn't have the mental maturity to think ahead and understand just what having a baby (or abortion) actually entails.
So no, it has not "occurred to me" that they're having sex for the same reason we are, because they're not.
