me and my partner have a happy open relationship. however, he is currently in jail. For privacy sake the most I will say is he is being charged with things that didn't happen according to the police reports, and his lawyer says he has an excellent case for a lawsuit once he's out.

during a visit he asked a simple enough question: Are you getting any?

he asked playfully, I said no but someone was interested. I was about to tell him who, but he cut me off. He told me he was fine with me doing whatever while he's away (as we both have very high sex drives and when together we probably have sex once or twice a day, more if we have the time, so usually there's no time or desire for other partners) but he does not want to know when or with who it happens while he is in jail. He simply said "use protection and just be safe honey, but right now we aren't able to communicate regularly, we call once a week and I want that time to be spent talking about us,"

I asked if I should tell him after he's out, and he said no as he thought the circumstances of it might make a hookup with simple intentions into something complicated, and that it wasn't complicated. He's away, we're open, as long as I'm safe about it he doesn't want me to tell him right now.

This isn't a foreign boundary to us, as we find certain things awkward to share. While we were long distance our sexual updates were usually a simple "I hooked up with someone" "GET IT HUN" with not much elaboration unless there was a good story behind it.

Now recently, I did hook up with someone, a good friend with whom I have no romantic attraction, but it's caused me a sense of guilt because I haven't mentioned it to him out of respect for his boundary.

What should I do, because on one hand he specifically asked me not to tell him, but on the other hand I want to tell him to relieve the guilt. Should I feel guilty? Should I just be celibate for simplicity's sake? Did I do the wrong thing?
