A good equivalency, IMO, is to imagine how many guys are into ridiculously big-titted women. I'm talking the surgery type nutjobs who have breasts as big as a couch.
What guy really wants to date that? It's out of fuckn control. You could never take that woman anywhere, she would be an absolute freak show.
Could you introduce someone like this to your family? How about your kids, or nieces or nephews? Could you even take her out in public?
I know you can make the big tits are great joke (ho ho ho), but seriously, how would you possibly cope in day to day life?
Sure, there will be some weirdos who think it's great, but most guys are not interested in any type of relationship with something like that.
