For ****'s sake... For the people who are misinterpreting this post, either accidentally or maliciously: THE. GF. IS. NOT. CHEATING. ON. HIM. SHE ISN'T CHEATING ON HIM. She isn't TRYING to cheat on him. She is, for whatever reason, trying to get _OP_ to either date or have sex with the guys. Note the wording- SHE'S INTRODUCING THE GUYS TO OP TO HOOK THEM UP WITH OP. That doesn't imply that he stumbled on them hanging out in a suspicious manner. It implies she is deliberately setting it up so that OP will meet and interact with the guys- as in, what people do when they want to set friends up to date. Don't just READ. COMPREHEND. Sweet Orion. The lot of you sound like you've either got a guilty conscience or had the worst series of exes in history.

I find it hilarious how many guys here find the idea that a woman liking two men going at it to be so confusing, like it's some super rare and bizarre thing, but no one blinks at the idea of lesbian ****. It's the exact same thing, guys! And it's WAY more common than you think! Now, it sounds like the OP's girlfriend might be being disrespectful because this is the second time but still...

Have you asked her why she's doing this? Maybe she thinks you're gay or bi, maybe she likes the idea of two men going at it, maybe she wants a MMF threesome (also a fairly common fantasy). If she does it again, point out that she keeps trying to set you up with guys, and what gives.

That's hot.

I'm 99% sure she wants a threesome. My ex tried that with me

I'm thinking she doesn't see herself as your girlfriend. No I'm not confused or disillusioned that maybe she has a fetish for gay action. Some of you out there are comparing it to guys and lesbian action. Almost but the piece that is missing is guys usually try to convince their girlfriends first; they don't just start introducing them to lesbians hoping they'll strip and start scissoring in the middle of the bar. The "girlfriend" instead is acting like the stereotypical helpful friend by introducing her friend, be them straight or gay, to potential partners without talking to their friend first about it.

You should try it. You might like it and if you never try, you never know what you're missing.

Guys. Girlfriend doesn't always mean a relationship. It could mean a friend that is a girl. It might not be but it would make a lot more sense

Um are you sure she knows she's your girlfriend?
