I'm at 8 months on HRT as of a couple of days ago.
As for why, the short answer is to find that piece of myself that's been missing since puberty.
A hormonal transition always felt like something reserved for trans folks. I knew I wasn't a cis man or a trans woman, but those were my only options in pre-Internet Texas. I told myself I could put up with it because I didn't really have a choice, and for far too long, I didn't.
Learning that amab enbies given the choice to tailor their protocol actually do report benefits from HRT was part of a series of significant coincidences and happy accidents that finally got me out of Texas for good.
Once I knew it was an option, it was as if the reality itself conspired to lead me here. Seriously. It'd take me half an hour to type out just the chain of events that culminated in my partners' accidental adoption of a heat-stressed street husky which got them on board with moving north before I could even broach the subject. I find it's best to listen when the universe is giving such a clear signal. XD
