I once knew a gal who, on first meeting her, I thought very highly of her. She had a wonderful personality. She was smart, clever, witty, charming. She was also very beautiful. The illusion didn't last though. She openly admitted to having "well over a hundred partners...honestly I don't know because I stopped counting at 75".
Ick.
In that moment, a rare thing happened, and I knew exactly what I wanted to say and I had the opportunity to say it. My words to her were "I appreciate your honesty. I cannot and will not be involved with a woman who has had that many partners. To me, it shows a lack of self control and a lack of self respect. If you think so little of your sexuality to give it out so freely, it isn't worth anything, and I see no reason why I'd want something worthless."
That was probably the only time in my life I felt good about being a frigid prude.
