Sorry for the unclear writing. No, my ex-wife and I aren't having sex now, but she did and I assume still does, enjoy an extended session. My current wife Daniela and I are part of a closed group of married couples, so we all strictly do not play outside our group.
My ex and I did, however, have sex during and for a while after our divorce. It was easy, familiar, and convenient for the both of us during that busy time in our lives. It goes without saying that bad sex was not the cause of our divorce. There was a short overlapping time when I was fucking both my ex and Daniela before we got married. Daniela knew what I was up to and as I suspected and later confirmed, Daniela was doing a farewell tour with a few partners before we decided to get married and become monogamous. For a while. I was happy that way, but recognized that Daniela needed variety and more sex than I (or any one man) could provide, so it was my idea to let her hotwife at first.
I can go a long time and stay hard, but have some difficulty orgasming. Mostly, I enjoy the prolonged ride. When I get the cue that a woman wants me to cum, I can concentrate and ejaculate.
