There is no male contraceptive pill. Men can also get taken advantage of, like in the case of a 15 year old boy who was seduced by his teacher. That boy has to pay child support now.
It's hard to argue he was forced, though. And child support mainly takes into account who's the parent of whom, and well, he is the father of the child.
Seduction of teenage boys by adult women is both ridiculously easy and quite rare at the same time... One of the few crimes were the victim thinks he got lucky...
And child support mainly takes into account who's the parent of whom
Actually it mainly takes into account the woman's wishes. If the woman states that X is the father and for some reason the X doesn't contest, he's in dock for child support even if he is not the father. This is a despicable law, along the lines of "black people are property" and needs to change pronto. Why do you keep defending the indefensible? Why do you hate making the world a better place?
One of the few crimes
It's not a crime in the first place. Sexual activity should be encouraged. What is a crime in the first place in the example is that the woman coerced a man into fatherhood without prior written impregnation consent.
