Hi Jennifer
It seems what you (and I) feel is quite common. I too want to be in a woman's role if I was to be with a man and don't want gay sex. Through my life as a cder I felt varying degrees of attraction to men and wanted a man whist dressing. I would say it falls into a categry of wanting to be in a female role. If you're feeling feminine I think it's natural to want to play a female role in sex.
