Doesn't have to be that way..
I know 25 y/o guys who have never been in a relationship. They are more innocent than any 16 y/o girls I have ever met ^_~ And it would be a piece of cake for a 16 y/o to manipulate and take advantage of them.
I think the parent should meet the guy before judging him. Too late it seems..
ROFL
But these 25yos prefer their porn
