It seems to me like all girls think they can get really attractive guys. I see unattractive and fat girls lust after built and muscular guys all the time, and while fat guys do likewise with hot girls, no fat guy believes he's ever going to actually be able to get the hot girl of his dreams. Many unattractive girls do seem to believe this, though. That's why so many girls are single. It's not that they can't get a guy, they just can't get the ultra hot guys they really want, so they abstain altogether.
