What's a Sissy?

To be clear, I am Post Op MTF. I am not sure that I am transgendered save to say that my experience with males was dismal and I hated them. I have never had sexual relations with anyone save my wife when I was married.

I am reading a story where a guy is being Sissified, but has a female fiance. Make your head spin? The reason my original marriage ended was I was too feminine for my X. She felt I was gay. I am not.

I present as a woman now and have for 18 years. I don't think Sissies are gay. Perhaps the people that insisted that I transition were simply incredibly stupid?
