I’m the ultra ultra jealous type - I can’t even stand it if another man even lightly touches my girlfriend(s) - I can’t even imagine sharing her with another man.
If she would want to explore things with other women - I see absolutely no problems there
From my end I don’t mind other women - if the girlfriend(s) in question are fine with it.
I once “spun plates” - dated multiple women when they all knew about it but they were exclusive and monogamous from their side.
Got too confusing and draining after a point - then thought monogamous relationships are The Thing.
But I’m not so sure about that either
