I also find it fascinating that bisexuality is vastly overrepresented here

I'd be interested to see the orientation numbers broken down by sex/gender. My personal experience is that geek/nerd women seem to be bisexual at surprisingly high rates. I'm wondering if having typically-male personal pursuits (e.g. LW) is correlated with typically-male sexual interests (i.e. liking women).

he would rather be bisexual than straight, because it would allow for more opportunities to have fun...(I personally also share Eliezer's attitude, but unfortunately I'm pretty sure I'm straight)

I'm in that boat. Feels like I'm missing out on half the potential fun. :-(
