My wife was in her early fifties when she took her first black lover. We had both been fantasising about this for many years beforehand. She came very close to doing it when she was 48. She went back on birth control in readiness but circumstances (lockdown) stopped it from happening. Well, in reality it was put on pause.
There is certainly something highly appealing about interracial sex for her (our) age group. I suspect the social taboo that was more prevalent when we were younger created a more intense desire. Interracial sex is more normalised now, but still a very wonderful thing.
