Ironically, I was just on yahoo answers and came across a 22 year old girl who says she prefers 16-20 year old guys. She looks attractive in her pictures and her answer got a thumbs up. I can say with complete certainty that people do not have the same hostile towards this as they do towards a 22 year old guy and a 16 year old girl or even a 30 year old guy and a 22 year old girl. Really, I think it has nothing to do with 16 year olds being too young, and that it is just part of a general disdain for men who get involved with younger women. If there was a law saying it was illegal for men over 30 to have sex with women under 25, most people would stand behind it 100%.
