NC for this.
My partner and I have been together for 8 years and we have an exceptional sex life. We are both very open in what we want, fantasies etc. I am 38 and he is 41 if that is at all relevant.
Recently DP suggested we tried invited another man into our relationship as he really wanted to see me be intimate with someone else. He wasn't interested in being with another woman himself. Being completely honest, I wasn't really into the idea at the beginning but after a lot of discussions and the pros and cons I came around to the idea.
It was all arranged and went ahead.
I won't go into the gory details.
Problem is, my DP is now regretting it happened. He regrets suggesting it and he really didn't enjoy any of the experience. He should have said at the time and I would have obviously stopped it. We had agreed if either of us was really uncomfortable during we needed to say. He said he didn't want seem stupid for suggesting and going back on it.
He feels like I enjoyed it too much and has opened a whole can of insecurity worms and I really don't know how to navigate this.
Any ideas would be welcome.
