Never kept count so I have no idea - didn't know this was going to be a test question.
But I have definitely turned down lots of offers. In bars, at parties, on the beach, on the street, in the gym, etc. I often get unsolicited offers for sex by a wide range of people, male and female. I turn 98% down. I have a need to get to know a woman personally before I have sex with her. To build an interest and desire. Recently in a discussion with friends we concluded that I average one new sexual encounter for every 50 I turn down. So I would assume that my "numbers" are a lot lower than most people.
