Nostalgic man here, thinking back over the very last time I had sex on each occasion in the various established relationships I’ve had over the years.
Many I’m unable to remember because usually you can’t predict when the relationship will end eg cheating on either side was discovered, or the relationship just drifted and we didn’t really know when it ended.
I can’t remember the final time we had sex when I was married. Perhaps because it would have been loveless and lust-less, and because after the last time we then went a year without sex before moving to separate bedrooms.
One relationship ended very messily, when we were engaged to be married but she was being unfaithful with a married man still living with his wife. She kept bouncing back and fro between him and me, and the final sex we had was very much my persuading her, trying to keep her. She gave me pity sex.
One relationship ended when we were on holiday together, and I had earlier been unfaithful. My partner and I had been arguing. She wanted make-up sex so we did, and became angry because although she came a number of times I deliberately did not cum. It angered her. I think she saw it as controlling.
Another was when my partner had ended the relationship and I couldn’t accept it. She was letting me down gently. I stayed over at her place on a few occasions after she said it was over, and on the very last occasion she allowed me to fuck her -pity sex again- and although she was very turned on she did not allow herself to cum.
My very last relationship ended this year, and I remember very well, it was brilliant morning sex. Then later in the day we had a huge row and it was all over.
I have never had a relationship end where we then carried on having uncommitted convenience sex until we found new partners, although I know that’s not unusual.
