For simplicity, I always choose bisexual on these polls. I do not identify as bisexual, however. I identify as heteroflexible. I always feel like if the word bisexual doesn't actually imply an even split of attraction, it is certainly inferred by many. I am almost exclusively attracted to men for sex, living companions/housemates, and romantic entanglements.
I'm not attracted to most women, even if I can see they are attractive. I also have no desire to ever pursue a romantic relationship with a woman, or anyone else who isn't biologically male, and happy about it. I'm just not wired that way. I only like living with men, too.
I can suck it up, and make living with women work for a while, but eventually I become extremely territorial about my living space, and I want the other woman or women to leave. And if they mess with my kitchen or crafting space, I will (internally) freak all the way out.
I love having friends. I will befriend anyone without regard for their sexual or gender identity. But I can't see fucking most other people, and when I am interested, he is almost always a guy. I have had crushes on women, but not in the same way I crush on dudes. Crushing on a dude, I want to become his life partner. Crushing on a woman, I just want her to become my sister. I want to show her how very special she is to me, and get her to let me love her, but I want to love her like a sister.
So. I voted bisexual. But I personally identify as heteroflexible.
