When I was 50 I was “the young stud” with a couple in their late 70’s.
I was having threesomes with a couple where the guy was in his 60’s and his wife was early 40’s, at one of my sessions with them the husband pulled me aside and asked if I would be interested in having a threesome with an older couple, he had been having threesomes with them for over 30 years and it was the older woman’s birthday coming up and the husband wanted to surprise her with a younger guy, he thought of me and the good times the three of us had together, so I said yes.
It was more so just the older wife and I doing it while he watched, she was still an very good fuck and put a lot more into it then some women half her age I had been with, no regrets this way at all.
My wife was 45 when she took a young 17 year olds cherry, they had been flirting on the CB radio for a long time, it was a case of her putting her age down and him putting his age up, which was fine until they met face to face, but by the time that happened they were too far gone to turn back, he sure left with a big smile on his face.
Usually we stick to partners in a 10 to 15 year age difference between us, but there have been exceptions to that from time to time.
