My first wife (long ago) shared her sexual history with me. She had been a virgin until she was a college freshman at 18. Over the next 4 or 5 years she likely had about 35 dicks. About 6 of them were on a post graduation western trip with a girlfriend. I know that she also had some involvement with a couple we knew that were in a regular swinging group but she never shared those stories. Unknown how many different cocks that was. After we married she soon went into some heavy cheating, likely 6 more. She then had a pass for 2 regulars for 2 years. Then a couple more cheats years later before we split up. According to many, she became a very active hotwife for decades, after she remarried. Mostly 2 and 3 on one sessions so her total count must be high.
My second and current wife had a long string before, after and likely during a very short first marriage and a much longer second. She was 40 when we met. Could pass for 35 or less easily. She and another similar aged and also hot looking girlfriend were really hitting the dance clubs. From what she shared, I'd estimate 50 or more to that point. Another cheater after a few years of our marriage. Three guys that I know of. She had a pass after that for several years, two regulars. Some years later she had a another cheat streak that turned out to be a good friend of mine. If he or she would have asked me, I likely would have agreed. No longer talk to him and got over it with wife. So maybe approaching 60 for her.
