We have not met with very many Black Men (7) but think that our experience range qualifies us to answer this question. The youngest was 20, and we met with him only once. There was no doubt that he had great stamina and quick recovery, but he was sorely lacking in technique/style and seemed to think that all he had to do was climb on and hammer her like mad until he ejaculated. He had very little to say and seemed to be interested only in his own pleasure. His age was 20, but sadly, so was his maturity level.
The other Black Men have been in the 35-50 year range and were very different from the younger one. Without exception, all have given us much more than we had expected when we started doing this. In the right hands, my wife is multi-orgasmic and these were certainly the right hands. To be sure, they joined us for their own sexual pleasure, but HER sexual pleasure was also of prime importance to them. After a ‘date’ she was sometimes quite tender but she also was sexually and emotionally a very satisfied woman.
We won’t say never, but in the future, it’s unlikely that we will choose anyone below the age of 25.
