I'm a guy and in my 2nd ever relationship with a woman we never had penetrative sex nor oral. We only ever did mutual masturbation together. I think ever since then I have developed a fetish where I like to watch porn where women are masturbating. In my subsequent relationships I like the idea of her watching me masturbate but I am too shy to tell her this. I feel if I suggest it she will think I am perverted. Any suggestions on how I can proceed?
