I would have a tuff time even dating a man I thought was promiscuous.
Would I marry a reformed slut? No, because one slut, reformed or not, is already enough to have in a marriage.
I dated a slut for thirty years, and it was a misnomer. She was promiscuous, all right, but it was not because she was a slut or she would have wanted to be. No. She had high morals, actually. And she was a lady. Unfortunately for her, she could orgasm for a whole half-hour, in fact, that was her norm when she had sex. So obviously she was hooked on it, terribly. Imagine a heroine high, or a crack high. That's what sex was for her. Of course the poor sweetheart never could have enough of it, and she screwed every tom dick and harry. I never put it to her, I never asked her to reform, I loved her. I was, in fact, proud of her, for allowing herself this self expression despite the values she had been raised with (Church of God Evangelist church etc. All her sisters got raped by their uncles and brohters, but my friend was too much of a little angel, they spared her.) She still is an angel, a person whose moral compass got completely out of whack because of the oppositionally storng pulls of the magnetic North of societal expectations, and the magnetic South of her incredibly strong and lucky biology.
She never 1. used a condom, and 2. got any STDs. Incredibly lucky girl. The angels watched over her, I am convinced.
You, OP, I'd consider lucky if you could marry a slut like that. I still can't believe how lucky I was to have dated her.
She was gorgeous all her life, she still is. Incredibly.
