I wish you had written more about your very “strange” desires. It would have been interesting to know more about what you’re fantasizing about with regard to gay men. What interests you about them? What information are you hoping they’ll share with you? Without more information it’s difficult to “categorize” you.
It is common for males to be aroused by the idea of two females. Logically this makes sense. Heterosexual males desire females. The more the better; two females are better than one. In your case the same logic may apply; if one male is good two may be better.
Generally speaking there may be women who are interested in the sexual lifestyles of gay males. They may find some of the sexual behavior of gay males erotic. Some may find the idea of two males a turn off and some may find it a turn on. Everyone is different and no one fully understands the science of attraction and sexuality. The bottom line is that there is nothing wrong with you. Don’t worry about belonging to a “category.” You are not abnormal nor are you a sexual deviant. As long as you are not engaging in behavior that may harm you or others then you’re fantasies seem harmless. You’ve simply found something arousing that may be less common than what other woman fantasize about. Consider yourself unique. Take care.
