These terms may mean something slightly different to each person, but here’s what they mean to me. I use these terms to identify myself, but they are just parts of my identity, not the entirety of my being.
I am pansexual because I find myself sexually, physically, and mentally attracted to persons of all genders (I believe that there are more than two genders, and I believe that the differences are gradual rather than a black-and-white distinction.) I sometimes say that I am “bisexual” since more people are familiar with that term, and for simplicity. I also am sexually attracted more often to guys, so I don’t mind the term “gay,” and I’ll use it in certain situations. But pansexual feels the most honest and complete, for me.
I am polyamorous because I believe that it is possible to love two or more people equally. I believe poly relationships can work, and that monogamy or serial monogamy isn’t the right solution for everyone. I’ve had one threesome, and though it was short term, it was fun. I haven’t had the opportunity to have a long-term poly relationship yet. While it isn’t a must, and I would certainly consider monogamous relationships if the right person came along, I really feel that a partly-open or a poly relationship suits me best and is ideal.
I am genderqueer because I feel more masculine at times and more feminine at others. I have no current desire to have surgery or take hormones, and I don’t want to permanently “lose” or change parts of my body. However, if there was a magic spell that could switch me between sexes at will, I would use it in a heartbeat (and often). As it is, I’m simply too lazy to go through the grooming rituals to be a “drag queen” and I’m too shy to be a performer. I don’t agree with society’s definitions of sex, gender, gender roles, and gender stereotypes. I consider myself transgender (and strongly support the trans community) even though I’m not currently persuing changes to my body. After all, gender is between the ears (not between the legs).
