I'm husband #2, she married #1 I think she was 26/27. She said she cheated on him once. We met she was 35. She said she was somewhat promiscuous when she was younger, so were a lot of women/girls, after all, she's a product of the late 60s/early70s. Never would talk about her sexual past.
Then in a moment of weakness she says during her single years she had sex with more than 300 different guys, gave me an instant hard-on, then she goes silent and I see her thinking. She says probably closer to 500. Her words, her estimate.
She absolutely refuses to talk about any details of her past. I/we are missing out on all those wonderful experiences she can relive and we can enjoy 'together'.
