Hahaha very funny the comments. One of my regulars is very honest and upfront with me. She said she prefer mid-age (40-50) guys as they usually get hard enough for 1 round.

She said she likes to see me for the $$$, but she has to work too hard and it is tiring for her. (I'm in my late 20's and out of a 60 min session, we spend at least 45min in action).
