The reactions on this thing will be all over the place. You don't want your 15 year old daughter having sex with older guys. You probably don't want this guy in jail for ten years. This is what happens when society tries to get tough and creates strict laws. Is a 15 year old an adult? Absolutely not. And once you start let 15 and 14 year olds have consensual sex, how do you feel when a 14 year old is seduced by a 40 year old?
the guy is 17, that's hardly an adult either. he can't even vote.
Again, as a PARENT, I would make sure to educate my kids EARLY on how not to be "manipulated" by adults to do something they will regret, whether that be drugs, sex, or criminality. I don't need any law to do that.
