Tough question…. Actually not really. >30 all the way (or at least late 20s).
Now I admit, I’m a man, like most of you, and therefore am susceptible to the reflexive allure of a young female body. In the moment l, there is something that feels a bit like the “fountain of youth” when with a woman in her early 20s, where everything is completely smooth, firm etc, and where her body seem to defy gravity. (I suspect the ladies here have similar initial feelings about young guys, with washboard abs, dicks as hard as steel who can fuck all night and cum unlimited times.

). But that’s just one thing.
I’ve done this for a while and if I look back, almost all of the women I’ve wanted to see again, were over 30 (or at minimum late 20s),even when I started this, (when I was just under 30). Women who look after themselves in their 30s, 40s 50s etc are not only beautiful, but are much more likely to be able to relate to me, know what they themselves enjoy physically and be in tune with how I’m feeling and what I’m liking. And are very often are cool people to chat with and share a drink and/ or some stories/ common interests.
