I had a sexual relationship with a guy whom I was sure was bi. I was the other women as he was engaged and planning his wedding during our sexual relationship ( please don't get hung up on this aspect ) and he was living in his one bed apartment with another bloke whom was gay. But there was only one bed and on many occasions I left him asleep naked in his roommates bed with the roommate due home at any moment. He also insisted that he got first go on a new sex toy. I teased him throughout our 3 yr fling that he was greedy having a fiancee, a mistress and a boyfriend. He told me he was just friends with his roommate but there were things he would say that had me wondering, he also didn't rule out having sex with a man at some stage in his life, although claimed he hadn't tried it. But he's now settled down with one woman and has kids, so perhaps he found what he was looking for.
