Gender terminology for those who mean well

Vocabulary: childhood

A quick review of sex and gender vocabulary in a timeline form: In the beginnning, we’re a bit of DNA, and that has chromosomal sex. Over the next few months, this leads to our primary sex or gonadal sex (XX to female and XY to male, with exeptions of course). Somewhere in that timeframe, the brain, the largest sex organ, develops the brain sex, which usually follows chromosomal sex, but not always, and it’s probably not as binary and certainly less open to inspection. Research on this doesn’t appear to be extensive. (“Biological” sex is a vague term that assumes all these are the same, which they often are, but not always.)
