Reconciled but want other people too

Well I am going to break this down as much as I can. I 40f and my husband 41m recently reconciled. We have been married 18 yrs and what feels like a lifetime later we were separated up until April of this year total of 4 months. The sex was meh 🫤 and many other problems that had nothing to do with sex. While separated I got in another relationship, purely sexual… but basically I was myself and expressed myself sexually in ways I never had with my husband.

Where it gets interesting: husband is bi. I always suspected and he confirmed. I am fine with this no problem at all, I just wish he had come to me and told me, rather than completely stopping having sex or using it as ransom if we had an argument where he wouldn’t want to do it for months sometimes. I felt horrible as my sex drive has always been higher and in order not to have affairs I just kept busy ( I am sure many people do this).

Where it gets even more interesting: we have talked for hours openly since. I feel we are back on, and now have sex almost daily!!! I love it. All positions, all places we can think of and during we talk about our fantasies and what turns us on. Almost always is talking about being with other people. Or watching other people do things to either me or him. It’s a huge turn on.

Currently, I have asked him to live those fantasies and he is on board. I have told him exactly what I am thinking of as one of our big arguments was that I didn’t express things until way later and they blew up… and turned into arguments. So I am being very explicit.

So I want to be with someone else, periodically. I don’t want to end the marriage nor do I want to be in another relationship, I want to date other people go out there enjoy and come back. He wants the same. We are clear to each other that we are each others forever and there is no breaking this bond.

Anyone been in this position? I emphasize I want a purely physical connection, but with some conversation so I don’t feel it’s a complete stranger.

Anyone ever been in this situation with their spouse? Yes I was super young when u got married and pretty much not experienced… but I am now and so ready.
