IIN to wanna be a whore but wanna be mostly wholesome with my bf?

I had a friend who introduced her husband to chastity. He apparently wasn’t keen at first, but she lured him in. Sometimes she had him give her lots of orgasms and then told him he was going without and staying locked a bit longer, but overall he worked out he was getting a lot more sex. She would never keep him locked up more than overnight then in the morning she would have him satisfy her a few more times before letting him out for sex. He didn’t realise he was being played until much further down the line as she gradually increased his lock up and her orgasms and sexual satisfaction. Over about 4 years she increased it to the point he was locked virtually all the time. Then she told him she wanted to start seeing other men for sex, if he didn’t object she would let him out for sex twice a week. He apparently agreed but what he never knew at the time was she had been seeing other men nearly all the time anyway. The twice a week let out soon became once a week, then twice a month, then once a month, then less and less. Personally I didn’t approve of what she did, but I had known her since school and she lived in the same street as me. She would come round for a chat on the weekend and give me her latest update. Eventually I broke my friendship with her as I felt it was wrong what she did, but they are still married and as far as I know she still puts it about regularly, he never looks very happy but has stayed with her all these years. I’m telling you all this as I wonder if this is the kind of relationship you might want to end up in. She always looks very happy if I see her in the street. Personally I believe men should be in charge, but in her marriage it’s clearly her calling the shots.
