I had numerous, one of my favourite was after I had been seeing a rather slim girl with big eyes and we broke up, my mates told me they thought she looked like a praying mantis, and so I was stuck with "Mantis". Try explaining that nickname to new girlfriends...
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).
