My wife (f54) and I (m55) have been together for over 35 years. We moved in together shortly after she graduated from high school. When we were in our early 20s I asked her if she would be willing to participate in an MMF with my best friend from high school. We did and it was a powerful experience that set us on our course of experimentation for the rest of our life together. I have shared her many times over the years, with a few men and one woman. A couple of her boyfriends have taken very strong dominating roles in our home.

Over the years I have noticed that my bisexual tendencies have strengthened. At times I have the urge to wear panties, and I do. And sometimes I feel a need to submit, sexually, to an alpha male. Recently I have started to fantasize about being raped by another man. I even fantasize about cross-dressing (passable) and being seduced and made love to by a man. Usually, the fantasies are about my wife's boyfriends.

This feminization (or the fantasy of it) has happened slowly. When I was in my 30s it did not exist, other than curiosity about sucking a cock.

Are there other cucks who have experienced this evolution?
