So my wife recently started dominating me in the bedroom and making me wear a chastity and she makes me use toys on her during sex and she even does a little verbal humiliation. Telling me that I can’t last very long in bed and that my dick is not even big enough to feel inside her sometimes. I love it and she knows that I like it but I tried to tell her about a cuckold fantasy that I had years ago and she said you honestly want to watch another man fuck me? Well I told her it was a fantasy that I used to have but she didn’t seem very fond of it and she said she wants me to be the only guy she fucks.. How can I convince her? Any advice from the ladies would be most helpful because I feel like you could understand her better and how maybe I can convince her?
