The young nubile ones get me off with the visuals and tight bodies, but they can lack experience & skill. With age comes experience & confidence in bed, but over 35, I start to lose interest as they get close to my age. I feel as if they need to be at least 10 yrs younger if I'm paying.
So, I find the sweet spot is late 20s, young enough to give me the visuals I need and enough experience and sexy skills to get me there.
Each to his own, they say there is someone for everyone...I reckon demand tails off as prossies age, despite their protests to the contrary, it's a younger woman's game.
