It's part of the fantasy, but does it have any basis in fact? Are the ladies won over by promises of bigger and better orgasms?
I suppose if you look long enough, you could find an example of almost anything. I'm sure there are many motivations for the games ladies willingly play. Do any guys know what they are? We guys do have a reputation of not asking, and even when we're told, not understanding. If there are any ladies reading this blog, would you care to share? Just so we guys have it written down somewhere, you understand. :-))
