Wife wants to go to a meeting/party where there will be all girls. They meet to chat, have a few drinks and enjoy each others’ company. It’s not planned as an orgy/sex meet.

My wife has never gone to these parties. Either decided against it or couldn’t go because of other arrangements.

Now: Sometimes these parties end with them having sex. So we are told from other friends. Some leave early, others decide to stay and participate in the sex.

I’m okay with her going, but for context, wife and I never had sex without each other, it’s a decision we made in the lifestyle. She does say she doesn’t want to join in on the fun (not sure if that’s true, but it’s what she says).

I am however a little concerned she might get drunk and do something with them. I’m not comfortable with it and it would feel a little like cheating. From my side it’s a little jealousy, little insecuriry, but also because of our pact of being together, it’s “our” hobby and not seperate hobbies.

If turned around, she would never want me/allow me to do something like that.

How should I best approach this? Any advice?
