So I (M23) had a spat with my wife (F22) about one of her past sexual experiences. When she was younger, before we were together, she had a threesome with her friend and that friend’s husband. That alone isn’t so much what bothered me because I’ve been in threesomes myself that she knows about. The issue for me is that she’s still friends with this couple. I know on one hand it can be seen as somewhat immature but I also don’t want to have to talk to any other man my wife has previously had relations with no matter the circumstances as I’m sure she wouldn’t want to sit and have a drink with any woman I’ve been with in the past. I’m wondering was I completely in the wrong? Is there some rationality to my thoughts?
