Cal, can I ask about your hair? Because when I started out, I also stressed about it - I was like "it's long, but it's man-long, it's coarse and thin and that's because of testosterone".... This is kind of bollocks. How old are you and how much hair have you got? Because any open-minded hairdresser will tell you that there isn't a "hair binary", except for how many products women use and how hopeless men are with hair......."I wash it every day because it gets this-or-that otherwise" and all that.....i.e. the "hair binary" is societal and not biological.
So I'm pre-HRT, I'm 23, I'm unambiguously male in terms of biology and early-morning appearance, but I went to the hairdresser and said, "I'm trans, give me a female cut", and they did it, and gave me advice on how to maintain it, and well, it passes for female hair now, even though it's a bit thin (which a lot of ciswom have anyway).
If your hairline is dodgy, have a look at finasteride: it kills DHT, a type of testosterone which is the Devil and causes the M-hairline; and it can restore the hairline to some extent. Might be worth asking other finasteride-users first though, because I've heard mixed reports.
As for voice: do you want to sound like a ciswoman, or just less like a dude/androgynous? Because I've managed the latter, and it's not hard; though the former I think is a bit of a slog.....
Anyway, feel free to send me a PM if you like =)
