Excellent point and article. This word was invented by men who were rejected. It was always a misogynistic and cruel word. I have never cared how many people my spouse of over 33 years had.
I hope there were many, and all of it was great. I know our sex life is. The real question is why should men or women avoid any sexual encounter that turns them on as long as it is safe and consensual?
There are no guarantees a person's spouse will be loyal and not bring home a disease so there is no reason to not pursue casual sex and take every available opportunity. Life is short, sex is fun.
