As a transgendered individual about to go on testosterone, I have my own insecurities. "What if my voice still sounds female? What if even on testosterone, it'll be obvious to everyone that I'm trans?" I feel like a lot of these are inevitable, and that they don't make you a bad person. I feel a lot of apprehension and insecurity that I won't transition well, or that somehow, remarkably, even though I have intense body dysphoria, I will wind up being wrong later. I've heard that in genuine transgender individuals, that their brain scans will match more closely to the opposite sex. I wish that in some circles I could have a brain scan to "prove" that I'm trans, but honestly if my brain came up as female, that still wouldn't stop my constant dysphoria. But maybe my biggest fear is that once you're on HRT, as far as I know, you're on it for life, meaning that I'd be an eighty-year-old man still paying for testosterone shots and shooting them into my thigh. All and all, it is a lot of pressure.
I think that the course of action from me will be to continue on to start testosterone, as I imagine that there isn't a trans man who wasn't nervous at this point, and if I try it and find that it's not for me, I'll stop it immediately, but if I try it and it lessens my dysphoria and helps make me more secure of my outward presentation, I'll stay on it.
