I am bisexual and have been in a committed, monogamous relationship with the same woman for almost 10 years, so YES. I don't think being bisexual makes a man any more likely to cheat than if he were heterosexual. That's a giant misconception about bi people that I hope will change as people become less ignorant and more informed. If your bi male partner does cheat on you, chances are he would have been just as likely to cheat if he were straight, because he is a cheating dog, not because he likes both sexes.
Well I'm at least kinda bi, and the only women I ever dated I never strayed from. I'm long-term oriented towards women, despite the fact that I'm attracted to guys sometimes. For some reason, those feelings tend to fade into the background when I'm seeing a lady.
Yes, a bisexual man can be monogamous. I was completely faithful when I was married and our divorce had nothing to do with sex or sexuality. Bi guys are just like straight or gay guys -- some can be monogamous and some can't or won't be.
If you're bisexual, then yo If you're bisexual, then you're bisexual. Your sexual partner at the time, or your who you're in a relationship at any particular time DOESN'T change that. One doesn't simply go back and forth when it comes to sexual orientation. You can't be "straight" one day and gay the next. Sexual urges/desires can go back and forth, but that doesn't necessarily mean you're any more "straight" or gay.
Can a bisexual man be monogamous to his female partner? Absolutely he can, I am. Understand my wife and I do have another married couple we share our bed with. The four of us have an "open bisexual" relationship with each other. We all fuck each other, we all love our spouses and we're all just married to one...but we all have three sex partners.
Simply put, yes. I am bisexual and my wife is straight. It doesn't really get in the way of anything; I am her spouse, and I would never leave her or cheat on her...let along be polygamous. I still get attracted to men, and it's something we've discussed before. It was a scary conversation for me, but we agreed that our marriage was always gonna be sacred and that no one else would join into our relationship. In other words, we came to an understanding about my orientation but decided it would not come between us, or bring someone else into the mix. Also, I generally disagree with polygamy so that helps.
In short, the answer would be YES, a bisexual man can be monogamous with his female partner. I know a LOT of bisexual men will sneak around to get there needs/desires met (I'm actually guilty of doing this in the past on my wife). My wife doesn't have a problem with my bisexuality, as long as I'm open and honest... but cheating on her would (and has in the past) cause problems. She does understand (she's also bisexual) that as a bisexual man, I have certain needs/desires that she can't fulfill, and in the past she has said she'd allow me to persue a boyfriend, but that's NEVER worked out well. She always felt left out, betrayed, and even that I actually preferred to be with another man more than I want to be with her... So we came up with a compromise. These days, I use a butt plug and dildo. She also knows I watch quite a bit of gay (bareback), transsexual and MMF 3some porn. We also randomly check out women and men in public together, so neither of us feel left out
