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 you 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 questions in random.
"SHIT, why can't we have boobs"

but they get sexually attractive if they saw a breast sticking out :P saw yeaaaaaaaaaa!
