It varies and depends on what specific scenario I'm fantasising about. Sometimes, I fantasise about males. Other times, I fantasise about females. Even other times, I fantasise that I'm a male, with either another male or female.
I've always been curious about this. When you close your eyes and fantasize, which sex instinctively pops into your mind? Does it vary? Is it influenced by the sex of the person you're currently with?
Other because I don't fantasize about males, and can't say I really ever fantasize about females. My fantasies are just kinky ones with my partner. However, I'd be more likely to have a female pop into my mind during those moments than a male.
Usually men, but sometimes women It seems to vary based on hormones and whether or not I've met a woman lately who piques my interest. (I can easily conjure up the faceless nameless fantasy guy, but when I fantasize about women it is usually about real women.)
I usually lean towards fantasizing about women more, especially when I'm single. When I'm dating a guy, I tend to fantasize about guys more in general, usualllly of the one I'm dating. When I fantasize about a male, it's usually a person I know, with women, my imagination goes wild.
