I just found out my boyfriend is bisexual. He told me and I was shocked and I had no idea what to say or do. Everyone keeps telling me I should break up with him because he's going to cheat on me with another guy and that worries the hell out of me because I reeaaalllllyyy like him. I don't know what to do :| And by the way, you can't really tell he's 'gay'. Like if you looked at him you wouldn't be like 'he's gay' or whatever. I'm just worried. I don't know how to cope with something like this.

... I don't see the issue here? Just because he's attracted to men (as well as women) he's more likely to cheat? That's a terrible thing to think!

Men who cheat aren't determined by who they are attracted to. I'm sorry, but this confuses me. Straight men are JUST as prone to cheating so your boyfriend's sexual orientation has nothing to do with his likelyness to cheat on you.

What he needs from you is understanding and encouragement. If you're worried about this, talk to him. Just realize it will probably be hurtful to him. If this is the only "problem" in the relationship, I see NO reasong to break up with him.

I understand you're worried but I think you have nothing to worry about.

If he is a cheater then you break up, you can be a cheater no matter what "sexual" you are. Being bi-sexual is not an excuse to cheat if you are in a steady relationship.

So if he would be a cheater he would be one straight, gay or bi

Cheating is cheating no matter who he cheats with. Do you think he is prone to cheating?
How long have you two been dating and how long has he known he is bisexual?
How old are the two of you?
If this bothers you, leave him alone. Dating can be stressful but when you are uncomfortable about certain things why deal with them if you don't have to.
Be open and honest about your concerns.
