I voted other, here's why - when looking for a romantic partner, even though some of my male (as well as female) friends have come close to what I'm after, I'm just not biologically attracted to other men. It's the simple "sex" factor, even though I'm not out for just chasing pussy or whatever, I still do value physical attracivness. Though to qualify, not in the same way a lot of guys seem to. Yeah, boobs and asses are are fun and games, but more important to me are things like physical attitude, demeanor, emphasis on attire and vanity, the sorts of external things that tell you what a person is like on the inside - that's what I'm attracted to. If she happens to have nice tits or something, then great. If not, oh well.
So why did I vote "other?" Simple, because I'm currently on this "individualist" crusade of getting people to stop looking at gender AT ALL in things that are irrelevant (i.e., sports, insurace, skill at things that were once considered to be gender-specific like engineering or cooking), and to start looking at any given person's INDIVIDUAL traits (i.e., individual muscle mass and skill in the case of sports, whatever factors go into any given type of insurance, mechanical know-how and cullinary skill, etc.). Basically, I want people to stop making assumptions based on gender - for example to stop ASSUMING that just because someone is female they're going to be physically weaker than any given someone who is male. Even if it is true most of the time, it's not true ALL the time, and therefor gender should not be considered at all.
But as far as relationships go, my brain is hardwired to prefer the female body.
