I have to agree with Megan. Most of the hardcore lesbians I know are pretty man-like. And the good-looking ones I know only do it for show.
I used to go to this bar with my roomate on "Alternative Lifestyle Night" and there was this girl/guy that used to try to chat me up. I got really tired of her in the end and told her "Even if I was a lesbian, the point of being lesbian is to be attracted to girls, not girls that look like guys." I don't understand that really. I'm not trying to be rude or anything, but why do some lesbians insist on looking just like a man?
