The title may be a bit misleading a way, because I'm no stranger to group sex and having sex in front of other people. I've been to sex parties but have never done anything at them, just watched consensually. I've engaging in swinging and foursomes with my partner a few times before too. However, I've never had a threesome with just me my partner and one other person and I am feeling a bit nervous about it.

It's pretty layered, but the reason I think I'm feeling so anxious is due to the place I'm at with ENM and my partner right now. First of all, we've both had solo adventures before, but the last time my partner hooked up with someone was his coworker and it was sort of a mess. I didn't really have the verbiage to express my discomfort with the situation he chose to get himself into. And he argued a lot over the principle of getting to choose what he wanted without a veto. We've since started couples therapy to talk things through and it's been going well.

The person we are intending to have a threesome with is an old FWB he had before he met me. She's since gotten married and moved out of state, but still comes and visits every summer. Last summer she came to visit and we had a trio date. It was nice and we had a fun flirty vibe, but nothing physical happened. We've had a long-standing flirty relationship with her where we've sent pictures and videos of us and she's sent some of her. So the threesome is a long time coming.

It's not that I don't want to do this, it's just that with our relationship being in a slightly weird place, and this being my first threesome, I'm just so on edge. I don't know what to do in moments where I'm not getting attention, or how to act when I am getting attention and someone is not. It's so easy with foursomes because everyone is always getting pleasured at the same time. But I have no idea what the flow of a FFM threesome looks like. Any advice??
