My first roommate was a rugged, heavy set, bearded macho man. Couldn't figure out why we weren't allowed girls in the apartment, till I saw him at a Rest Area trying to hookup with a meat slinger (male hooker).
I later found out he rented too me because he was attracted and tried to talk me into a relationship. And I told him "dude the idea of kissing your hairy face just freaks me out!" He went on to explain how he became gay and started out hetero, then bisexual. He believed it was a predisposition that varied from person to person, which is why he thought he could convert me. I didn't care then what people do in the bedroom and I still don't. If you're not invited to the party it's not your damn business.
