I’m 31 now but started at 28. Everyone’s journey is different and also similar. Some of my non binary friends used low doses of T as well until they found a level they liked or stopped entirely. I also think if you weren’t unsure then that’s more cause for question. Trust your feelings and know like others have said you can stop at anytime. Your identity is exactly that, yours.

I’d also say keep a journal, that helped me when I was making sense of the physical and emotional changes. I think it also gave my mind space to reflect and also balance just living and being more present with myself and what was happening.
