For whatever it’s worth, shaving before meets was a very common thing among the men on my high school’s swim team; no one thought it was strange. I seem to remember a few elite swimmers even shaved their heads…
Personally, I find the hair removal process somewhat of a burden but I find the aesthetic results desirable (and the comfort when wearing tights; a stray hair on the knee or somewhere can be really unpleasant when you bend.)
Never have thought much about what it would be like to be a guy except for vague thoughts of “it would be a lot easier to be able to pee standing up” when out in the middle of a forest doing fieldwork. I pretty much like being what I am, always have.
I guess one of the fundamental aspects of my character must be that I got over FOMO at an early age. It’s true there were opportunities I later wished I’d taken, but as I said on the thread about parallel realities, the result of making different decisions would be someone else wearing my skin — and probably being less comfortable in it.
