Well, there can't really be a different thing for age difference for guys and girls, because if you say a girl shouldn't be with a guy younger than her, and that guys should go for older girls.. well it sorta wouldnt work. so to some extent they gotta work with each other. and personally age differennce is not a big issue the guy im with now is 7 years older than me. and ive been with older guys and i dont find it strange, neither does he, his friends or my friends.
