Aside from your definitions of sex and gender, I agree with everything you say. Particularly the alphabet soup.

I'm gay, I came out in 1974 in Norfolk, VA where the gay scene was mostly about drag queens. I felt no connection to them at all, and in fact most of them were thieving parasites. Let a transvestite into your house and valuables would go missing. They never worked and lived with a succession of soon-to-be-ex-friends from whom they stole.

Like many still adjusting I claimed bisexuality (it's not really common among men at all) but unlike most I had sex with women a few times.

Sex and gender: in my lifelong understand all matters of male and female, biological and psychological, are gender. Sex is an activity that most of the animal and plant kingdoms perform to reproduce and some high mammals do for enjoyment. Yes I have seen "sex" used to mean "gender"; then again I see "media" and "criteria" used as singulars every day,
