As a woman at 58, I am always flattered when younger men look, check me out, and flirt with me. I like younger men, and my lifestyle girlfriends call me a cougar. Not that I seek out younger guys, but I do seem to get a lot of attention from younger guys. Young guys are appreciative, get hard before their pants are down, and don't go limp until they cum, but they are almost instantly rock hard again and ready to go.
I have done a few 18-year-olds after making them prove they are 18, but I seem to enjoy those 22-32-year-olds most.
