I'm ambivalent toward being on T personally.
I think some changes might be a little cool, like voice change. I'm up and down about how much facial hair I'd want because my family gets quite a bit, so even close shaves still show the follicles underneath.
But at the same time, hanging around people who want higher voices and less/no facial hair has made me not want those features.
Idk... but I am quite dysphoric about my voice, not nearly as much so about facial hair, but sometimes it seems like it'd be a neat accessory.
I sometimes toy with the idea of being on injections for like 3 months (or whatever amount it takes for a voice drop, but not like waaaay low voice drop) then getting off permanently, but idk. I generally imagine I would use injections, but I often hear "gel/cream and patches are milder." I feel like I've witnessed more injection-used transitions, though, and that's how I've gauged my timeline (i.e of voice and hair, although I feel like every body's different so there really is no way of telling, but I feel like it's my best bet of estimation)
