Good, yeah if you're into that it's worth exploring the possibility (ie like how you talked with some women) but if you're not comfortable going through with it or have any sort of hesitation, it's a much better idea to leave it as a fantasy. I'd much rather have an unfulfilled fantasy than a ruined relationship. If it's something you decide you want to try down the road, that's fine, but only if you're 100% comfortable with it and you've laid down any rules/guidelines you, your husband, and the other girl may have. It should also be a rule that any of you can ask to stop at any time and everyone stops. It's OK to back out after you've already said yes if you're not feeling comfortable anymore.

I have threesomes/small gang bangs with my SO (only (M)MMF though) and he always picks the guy(s). I never contact/interact with the guys before or after and we never exchange contact info. That way neither of us have to worry about the other guys harassing me and asking to meet up with me alone. I would recommend setting rules like that if you ever try it, and maybe no PIV or anything the first few times. It's better to start slow to test the waters. Maybe have him just touch a girl and see if you like that before you do anything more intimate.

Ohhhh, and exhibitionism can be fun. I cam sometimes with and without my SO. If he's not on with me, he watches and is the mod in my room. He loves posting pics/vids of us on FetLife like I'm his trophy haha. I workout a lot and I take steroids/peptides/etc so I'm in very good shape, and without sounding arrogant, I'm pretty conventionally attractive, so he gets to feel like the stud that got the hot girl.
