My ex and I played in the lifestyle for many years, played with couples.
Then, although at the time it was not Hotwife, it was called sharing, we began inviting others into our sessions.
This was all good until after around 25 years of playing with couples and singles she said she did not want to do it anymore, not just with couples but with anyone. I said that's ok, but after about 6 months she decided that she just did not want to have sex anymore. Thought ii was menopause but she would not have sex with me unless I demanded it, then after a bit she just gave up on sex and said if I wanted sex to get a GF or hire a hooker. That is why she is my ex.
She was totally into sex with couples or with men in general. We had a few single ladies join us and it was good for both of us. Went to therapy and that did not work, so we finely split.
The good thing about that is I met CC.
