Hey dude, welcome to the forum!
Yeah, this stuff is totally confusing, especially if your going through your teens, which are a rollercoaster even for cisgender folk. But it is also the best time to deal with HRT- so good timing! Just know you only have to ask and we are all behind you. We certainly all understand the situation! And hey, don't just hang with the ftms- scruffy bunch of bad asses they are, do come say hi to the mtfs from time to time too! Lol.
