IT'S the same reason why girls like to look at guys six packs and dicks. It's something that's attractive to some men. Not all men. WTF are 你 trying to say?? Some girls are lesbians. I like boobs because they are attractive on women. In fact I like every part of a women. I'm seriously getting tired of all the dumb sexist 问题 in random.
Because women with larger breasts are 更多 likely to breast-feed 婴儿 sufficiently. So unconsiously, men are attracted to them. It's all about producing healthy offsprings.
^I didn't say anything about butts, legs 或者 faces. I just gave the psychological/scientific explanation on why heterosexual men tend to go crazy about boobs in particular.
there like "SHIT, why can't we have boobs" :P JK JK but they get sexually attractive if they saw a breast sticking out :P saw yeaaaaaaaaaa! hahahahahahahahahahahahahahahahaHahaha xD ask this 问题 in (sex and sexualty) 0.o
cuz they r horny lil beasts but 嘿 gotta luv em right n not only men like boobs there r some bi girls (like me) n 女同性恋 that like boobs (but i rarely get attracted 2 a girl)
Because some guys find them attractive. Not all men are boob men. Some men like legs, eyes, lips, butts, vajayjays, bellies, hands, feet, arms, ears, noses, all guys are different.
