And this.
Many people (mainly homosexuals who grew up being told homosexuality was "wrong" and heterosexuality was "right") have tried to "switch" sexuality and it made them miserable, because they were trying to be something they weren't. Same with straight women who have a bad experience with men and experiment with women. They might enjoy it for a while but ultimately they will go back to men.
When I became aware of my own bisexuality a few years ago, I was very uncomfortable with it, because I had always believed myself to be straight. I didn't see anything wrong with being bi, but it scared me. So I tried to "stay straight." But in the end I just accepted it, and now I'm bisexual and proud.
