I don't know how I'd feel about being in a long term relationship with a bisexual girl. Even if she promised to be faithful and kept it (I'd never be in an open relationship, if I were to fool around I'd expect to get dumped, she should expect the same), I think I'd still be insecure because I'd know there's always going to be sexual desires she has that I could never fulfill. I like to be able think I at least have a sporting chance of fulfilling all my woman's desires, lol!

I'd just rather just avoid that issue, there's plenty of nice straight girls out there, but I suppose Lex is right, you don't choose who you fall in love with
