Been with my GF for just over 2 years we met through swinging and started off with an open relationship. January this year I could tell she didn’t want to be open anymore, she hadn’t seen anyone by herself for a while and although she wasn’t saying it I could tell she was getting upset with me seeing another woman regularly. We spoke about it and she said she wouldn’t ask me to stop but it was obvious she wanted me to so I did and haven’t met anyone without her since. The truth is I’m missing my solo adventures, we meet other couples together but the sex is mediocre at best and I feel most of them are there to play with her not me. I want to talk to her about it but I don’t know how to bring it up and I don’t want to upset her.
