For the purposes of this group I don't think you need to know my sex or my gender. The only person who really needs to know my sex or my sexual orientation is someone interested in having sex with me. Someone who knows me personally will know & if we ever meet you'll get the chance to find out.
If you address me incorrectly why should I get mad? I don't you to expect to have ESP. If you are worried about the possibility of insulting me or anyone incorrectly, learn to use genric insults that don't depend on sex at all. Lacking guts instead of balls, etc.
