I am constantly approached by men who are somtimes more than ten years my junior. And I am flattered, but I don't think that I could do it. I mean, what would we talk about after sex? Pokemon? (Not intended to put younger guys down AT ALL.)
I am only expressing that our lives are so different. It is extremely rare that I have met a younger man that could relate to me on any level other than on a sexual level. I have ZERO interest in pursuing a very serious relationship with ANYONE, but still in order for the sex to be remotely enjoyable for me some sort of connection must be established.
I am very attracted to men that are my age and older.
As for stamina, my last lover was one year my senior and he had AMAZING stamina and technique. I seriously doubt that I will EVER find another that could even touch him - ON ANY LEVEL.
