I kind of had acceptance of hairloss, but in reverse. It started in earnest around 16/17, slow and gradual but hairloss none the less, my dad was bald, my next oldest brother was bald, I accepted that I was going bald. That is until around 20/21 where I freaked and suddenly looked like total ****, I guess I accepted it until it made me look ugly. I really am a case where I look pretty damn attractive with hair, (or the hair I had) and hideous without it, (I couldnt even dream how bad I'd look completely bald.) and no I dont think I have body dysmorphia either.
I will be 22 in a few days, without a gf for quite awhile (interestingly, about as long as my hairloss has made me look like ****), so this is why I personally obsess about regrowing my hair, it changes me from ugly to not ugly, and if I had total regrowth-handsome, which I deem a highly important factor in attracting a gf (that meets my standards)- one of lifes most important goals.
But im sure there are plenty, if not the majority of fellow male pattern baldness sufferers out there that dont have such a major impact on their appearance, if I was one of them I would surely not obssess.
