Would you have more doubts concerning the monogamy/loyalty of a bisexual partner than a heterosexual one?

Not at all, it depends on the manner of the individual in the first place, you're either a cheater or you're not, sexuality has no effect on it what so ever.

I am sure it is no easier or harder for a bisexual person to be faithful than it is for a heterosexual. I guess if I was your heterosexual partner I might feel as if there is twice as much competition to worry about.

Is there twice as much temptation for you?

I am bisexual, and have never been unfaithful to a partner. I am married to man, but wouldn't dream of betraying my bond with him.

He has complete trust in me, and knows that yes, I love females as well, but I am devoted to him :)

When my boyfriend and I first got together he was a little wary about it. Especially when going to visit my parents, and my ex girlfriend was around. Now hes over it. Its been 3 years, he knows even if I find women attractive I'm with him, not anyone else.

I don't think it has anything to do with the person's sexuality; it varies from person to person and is completely an individual thing.

But I thought eatin ain't cheatin!?!

just the candidate pool of POTENTIAL candidates is double but if you're inclined to cheat, you are inclined to cheat, gay or straight or bi

Too often bi sexual people think it's okay to have sex with the same sex even though married. It's still cheating in my book.
