The best way to know is to ask him and open up that discussion. If he denies it it, ask yourself if he could be having an affair with anyone. Honesty is the best policy. If you have questions then just ask him. You may get a feel for his honesty based on the way he reacts. Don't go into the discussion having already made up your mind. Give him a chance to address your concerns.
You already suspect him, or you wouldn't be asking. What is making you suspicious? Share this here on WikiAnswers, and we'll help you figure out what's going on.

Ask him right out
Well if youre a girl and hes dating you, hes obviously not gay.
I do not know that but i am pretty sure he is not gay!
He kissed a mural friend of ours who is gay on the cheek, I know it is only on the cheek but I feel like a straight man wouldn't kiss a gay man on the cheek, wouldn't that be giving him the wrong idea? My boyfriend says he's not gay and that it was just to be funny. My gay friend is now coming to me telling me my boyfriend might be gay. I don't know what to think.
When you catch him having sexual relations with another guy!
I do not know for sure. I have heard he at one time had a boyfriend.

Well, if you are a girl whose boyfriend, who also has a boyfriend, you ask him is he is bisexual or gay. Whatever his answer, only you will know if you want to continue as his girlfriend, his friend, or if you want to move on.
The only thing you can do. If you boyfriend is gay you have to respect that and let him go.
