I mean, I'm 21 and people keep telling me to go for the younger girls (around 17 years old) but I don't really like the way they think and tend to prefer girls around my age, even a little older. It makes things more difficult for me as there's this whole women-date-older-men folklore. And there are many more relationships in which the woman is the younger person. So, is it true that there's a rule that men should go for younger women (at least 2 years younger)? Or is it just something invented?
