My boyfriend has been with 2 men but claims he's not bisexual?

Well, I think if he didn't like dick, it wouldn't have taken but a single encounter with it to make things very clear for him.  By which I mean that he DOES, in fact, like dick, given the right circumstances... regardless of what he says or thinks.

A person's sexuality doesn't change.  If he liked dick at one point, and he liked ***** at another, then he STILL likes both, and will ALWAYS like both.  He IS, and will always be, bisexual.  (He's not gay, BTW - having had sex with you pretty much puts the cork in THAT bottle.)

BUT - that doesn't mean it's not possible for him to be faithful to you.  Just because a person is bisexual doesn't mean they have to alternate between male and female partners.  Most bisexual people develop an inclination one way or the other and stick with it.  (In fact, the majority of bisexual people stick with whatever they start with, and never even learn that they can enjoy the other, at all.  They go through life thinking they are either gay or straight, not bi.)

So - don't fool yourself:  He's bi.  Advice:  Explain it to him, too.  Then the two of you maybe can have a serious conversation about where this goes.  Think about it:  This isn't about his bisexuality at all!  It's strictly about his ability to be monogamous.  Being monogamous IS NOT made more difficult by bisexuality.  Sexuality and monogamy have no impact on each other - they're independent considerations.  People who can't hack monogamy will stray and those who CAN hack it won't stray, no matter whether they're gay, bi, or straight.  The question is NOT whether or not he likes dick - the ONLY question that matters is whether or not he can keep his own in his pants.

Been with 2 guys.  Went to counseling (we call that conversion therapy).  Trying to force himself to live a straight life because of the societal pressures around him and either being too mentally weak to deal with them or not wanting to give up his stable 'straight' life.  This is typical behavior of a gay man in denial.  

It seems there's some second-guessing there so he's obviously questioning it and struggling with his sexuality.  Hate to be the one to break it to ya but most straight men who know they're definitely straight have never been with 2 guys before.

Delete your Facebook too.  It ain't nothing but trouble these days.  Nobody needs to deal with that kinda harassment and scamming.  I would imagine it was probably just a message from a Nigerian prince wanting you to wire some outrageous amount of money before he would reveal the secret anyway...

If your sex life doesn't appear to be negatively affected, then I wouldn't worry about it if I were you. Being bisexual doesn't necessarily prevent someone from being able to remain in a committed relationship, and if you have no reason to believe that he isn't committed to you, then it shouldn't matter even if he is bisexual. There is no reason why this should have to become a barrier in your relationship.

Saying something don't make it so.

Ooooo, yuk!!  That's disgusting!!

I do hope that you are getting checked for STD's.
