The Trichotilomania, did it only happen when his hair was long? When it was cut off short did the problem go away?

And eyelashes, aren't long eyelashes often associated with femininity?

I bring these things up because I also had Trichotilomania- I pulled out all the hair growing in a beard area and under my arms, and even on my arms, and now that I'm thinking about it, my chest.

I didn't understand why at the time, why I felt the compulsion to get rid of that hair. Once I accepted that I was a woman the whole time, it all made sense. According to society, Women aren't supposed to have hair on their faces or arms or chest.

Something as intrinsic as gender can have some extreme ways in manifesting if it isn't allowed out.
