It is expected that the gm will tweak things here and there for whatever reason, its part of their job. Its considered a major faux pas for a player to look at the statblocks of monsters you are fighting.
This has some truth to it, but i do think there is an element of location based longing to my idea of home. Home is a place where things are the way you expect them to be. Its a place that you have crafted to your own specifications, a place where you can exist with minimal resistance and effort. A place to be at ease.
You could try Fetlife! Its not a dating app specifically, but rather a kink focused social network/forum. You can find communities for your area and interests, and a lot of people on there are poly.
I was in a similar spot at the beginning of my transition. Visible M and thinning up to a few inches back. I am now just over a year on HRT and my hairline has improved significantly. I still have the M, but its much less pronounced and the thin parts are filling back in nicely.
I also had major dysphoria about my hairline, but now its way better and I barely think about it anymore. The way it works as far as I understand is that damaged hair follicles will repair themselves but destroyed follicles will stay destroyed. When you start T blockers the damage should stop getting worse right away and then begin to recover slowly over time.
People keep saying this, but i've been following this community for quite a while now and its always had a fair chunk of horny posts.
