My wife is a retired provider. She has been under a lot of stress from family issues. Recently she met a former regular at a hotel bar where she had met with a friend. One thing led to another, and she wound up having sex with the former regular. She decided that the experience helped take stress from her and that she enjoyed it. It makes her feel good when she realizes how much men want her.
She told me that she will start having sex with various men on a fairly regular basis. She will remain a good wife in other regards but will not change her mind in that area. My choices are to put up with it or she will leave.
