relax he is with you, course he is probably Bi, but so what! He still comes home to you right? Besides pay attention and do the things he does, maybe he likes that and that will keep him from straying.

Well the fact that he gave another guy a ******* in the first place is a red flag in my book

Ok seriously, I don't know why I have to explain this to people. First, if you're in a committed relationship, don't have a threesome. But if you decide to, freakin discuss beforehand what you are comfortable with your partner doing and what you aren't, and be CLEAR about it. The middle of what should be an adventurous and bonding experience is no time to start feeling jealous, or as in this case shocked. You're in a relationship. You should know how to communicate this.

He cant be bi? Why not discuss it instead of assuming.

**** gay people

Its a little funny, im a bisexual boy and ive probably sucked more boys off than my gf, also deeper, and swallows. My gf didn't start to suck me until a few months ago and recently swallowing because it saw easier to clean upp the mess. She also barely can suck half of it. We have beem together over a year.

Of course guys give the best blow jobs. Bigger mouths, intimate knowledge. I don't know why straight guys don't do this all the time.

He's definitely gay.

You deserve it. Literally. You invited this to happen by participating in a threesome. Don't act surprised when they backfire!

Reality is seldom better than, or even as good as fantasy. Some things should stay fantasies. That said - if you are going to have a threesome you should definitely take the time to set ground rules what you're okay with and what you're not - but realise you might not know you're not okay with something until it happens - and you hate it.
