-—are immediately provided with "Oh, that means you're not a cis boy; you're a trans girl" as the definitive explanation. But it was a different time, then. Of course I had _heard of_ transsexualism as a thing, in the form of the "woman trapped in a man's body" trope, but, like drugs and sex, it wasn't salient to me as something that actually happens in real life, rather than on television. The idea that I might somehow _literally_ be a woman in some unspecified psychological sense, was simply not in my conceptspace. I knew I was a boy _because_ boys are the ones with penises. That's what the word _means_. I was a boy who had a weird _sex fantasy_ about being a girl. (Where "girls" are the ones with a vagina, breasts, _&c._)

+At the time, I had _no reason to invent the hypothesis_ that I might somehow _literally_ be a woman in some unspecified psychological sense. I knew I was a boy _because_ boys are the ones with penises. That's what the word _means_. I was a boy who had a weird _sex fantasy_ about being a girl. That was just the obvious ordinary straightforward plain-language description of the situation.
