I love my boyfriend very, very much. And I would never consider cheating on him. I'm happy in our relationship and I really think we could make this last.

But I can't help but wonder if we met at the wrong time....I'm bisexual, and really only was open about it a year ago. I didn't really have much time to have any sexual experiences with girls before we met, and now I can't help but wonder what it feels like. So instead I watch lesbian porn and try to fantasize a little, but I can't help but feel guilty, because I think if he knew he would be really hurt about it.

Edit: Perhaps I didn't make myself clear. My boyfriend accepts my sexuality, that's not the problem. But he was cheated on (multiple times) in the past and gets jealous very easily, and wouldn't feel too happy about me thinking about other girls, even though I wouldn't act on it.
