Read entire obituary in above link, or this very great paragraph on sexuality taken from the article.
Swartz, who had both male and female lovers, wrote eloquently on his own blog about why he wouldn’t label himself bisexual or gay.”Having sex with other people of your gender isn’t an identity, it’s an act. And, like sex in general among consenting adults, people should be able to do it if they want to. Having sex with someone shouldn’t require an identity crisis….People shouldn’t be forced to categorize themselves as ‘gay,’ ‘straight,’ or ‘bi.’ People are just people. Maybe you’re mostly attracted to men. Maybe you’re mostly attracted to women. Maybe you’re attracted to everyone. These are historical claims — not future predictions. If we truly want to expand the scope of human freedom, we should encourage people to date who they want; not just provide more categorical boxes for them to slot themselves into. A man who has mostly dated men should be just as welcome to date women as a woman who’s mostly dated men.So that’s why I’m not gay. I hook up with people. I enjoy it. Sometimes they’re men, sometimes they’re women. I don’t see why it needs to be any more complicated than that.
