I am early 30s and have a few plates right now. All know I am seeing other people, though I don't go into details.

  • Francine: 34, single mom. No desire for LTR from either of us, we both know we are just having fun, and we are actually good friends and share a larger friend group. I see her a few times a month.
  • Sally: 32, former coworker. Great body, average face, very cool and smart, but not interested in an LTR with her since I don't want kids for at least another 5 years or so. I have told her this, but I get the feeling she wants to settle down soon (tick-tock). I will continue to be honest with her and spin this plate until it breaks. I honestly just want someone younger than me if I settle down. I see her a few times a month.
  • Amy: 29, ex GF, single mom. Probably best GF I have ever had, but I ended LTR with her because of kid. I didn't want to lead her on thinking we were going to get married, and honestly feel like I did the right thing. Since we both know we will never be more serious again, she is now looking for a provider and fucks me while she searches. We even joke about it haha. I see her a few times a month, sometimes spending a weekend with them fucking and watching Netflix.
  • Jackie: 23, just graduated college, studying for the MCAT and doing internships before applying to med school. Unless she gets into a local school here she will be moving in the next 9 months or so. I see her about once a week, sometimes spend weekends with her, and we usually do couples things or go out to dinner before fucking.

I am not interested in an LTR with any of them except maybe Jackie. That said, I would only enter an LTR if I could fuck other women because that is what I want to do right now. That is a pretty hard sell, but I would like to talk Jackie into an LTR where we fuck other women in threesomes when she brings up exclusivity (I think she will). She has made out with other girls when drunk before, but nothing more than that. I still haven't had a threesome, but she doesn't know that (frame). Jackie, while initially experienced (1 guy before me, good family upbringing, etc.) is open to a LOT with me and loves me "teaching" and "corrupting" her haha.

Jackie recently started asking me what I am looking for in a girlfriend. Last weekend, she made a joke about "us, or whatever this is..." at dinner. She has known I am seeing other people since the start (~5 months), but I predict she will bring up exclusivity in the coming weeks. Now, I can easily deflect and continue fucking her for a while, but I try to be honest with my plates and actually enjoy Jackie's company.

Any "relationship" we would have will end anyway when she moves for medical school. If she stays in town for school and it doesn't, I could continue seeing her while fucking other women with her or end it before then if I get bored.

I realize one can fuck other women outside of an LTR, but given Jackie's career ambitions, age, low n-count, and overall pleasantness, she is LTR material and someone I could see myself being with exclusively a few years from now when I am ready for a family and something more serious. In addition, she is a lot of fun, and could be an asset when I travel (she speaks like 6 languages fluently and could help with fucking locals). Plus, since most of my closest friends are married or in relationships now it would be nice to have someone to bring to all the couples events that I actually like.

I just can't do complete sexual exclusivity right now. I never thought I would say this, but having a girlfriend that I fuck other women with is exactly what I want right now.

Has anyone here successfully talked an LTR into something like this before or at the start of the relationship? There has to be a good way to frame "sure, we can be exclusive if we do threesomes together", right? If I do this successfully, I will more than likely lose Sally as a plate forever (no biggie), but I could probably keep Francine (and possibly Amy) in the threesome rotation.
