i'm a pixel here, myself

[This] is fascinating. And contains a lot of information about gayness and development than i ever knew. It also (inadvertently, possibly) backs up my distrust of bisexuality -- when you test what gender men's genitals respond to, they only have one: men or women, not both. (Yes, yes, exceptions to every rule, etc.)

On the subject of the "causes" of sexuality, I'm pretty firmly in the "lots of factors" camp. I think there's a large genetic component, considerable influence from hormones in utero, and at least a little influence from the way you were raised. Still, for whatever reason, I love reading stuff like this.
