I am not a female but can add that my wife was very faithful to me for the first 20 years of our marriage. I met her as a virgin and I was the only man she ever fucked.
I had to beg and convince her to fuck other men. She refused for years so to get her want other men I cut back on sex with her. I just wanted to get her to be horny longer and then not satisfy her. After a few years she gave in and said yes to fucking other men.
Now she doesn’t even think about fucking me anymore. We are more in love now than ever and she is more sexually satisfied than ever.
