You cant, so you should always listen to the case itself, and the persons who are involved... and not just look at the numbers and go:' ow... she's 15, he's 18+, this is WRONG!!!'. It's not.
Also, it's funny how women always say girls are always so much more mature than men at that age (13, 14-15 etc), but when it comes to this issue, suddenly it's a case of little girls who have been taken advantage off...
I feel even children should have brains to know what is right and wrong. Its also a case of the parents responsibilty to raise their kids with morals etc. When I was 13-14 there were already a bunch of girls who were at least ready for sex, and some who were already doing it, and usually with guys older than they were...
We should stop pretending girls of 14-15 are innocent lil girls. It differs from girl to girl, obviously, but most are already in a phase where they want boys and love and sex etc...
Obviously, it would be best if they went through that phase with boys their own age, but a 18 or 19 year old boy witha 14-15 year old girl, really isnt that big a deal. Not to me, anyway.
It's weird that we make a huge deal about teens having sex with young adults, yet whenever a 40-50 year old guy fucks a 18-19 year old bimbo, it's suddenly okay...
It is btw, cause if a bimbo wants to whore herself around like that, that's her choice. Just dont ask me to have any respect for her.
Personally, I want someone who is at least close to my own age. I cant imagine now being with a girl who's 20 or younger. Although I guess there are 20 year old girls out there who ARE 'mature' and my type.
Maybe when I'm 40 and having my midlife crisis, I'll be cruising for young chicks. But now I just cant imagine it.
