I’m curious about this research; my personal experience is that diabetes caused (unwanted) weight loss, so source? Admittedly, mine originated from another disease, or the treatment of it.
Anyway, back on topic, as a potential consumer of this data, I have to say birth gender isn’t a terribly useful data point. It would be much more interesting/useful to know which pairings players were interested in seeing/reading, and which role (if any) the PC would be playing, rather than trying to infer it from the other data.
EDIT: I’m male, but I often “self-insert” in games as a female (not just in fetish games) and would appreciate m/f and f/f pairings involving my PC. I’d be up for my PC observing m/m pairings, because, done well, that pushes my buttons too. Sexuality is complicated, and this is the kind of nuance that this and other surveys don’t capture.
Obviously one take-away from this is that designing surveys needs to be done with care.
Perhaps a better option would be to just share the results here for all to see as other surveyors have in the past.
