So, based on the answers I got I realized that I am most likely trans. Therefore, I started experimenting:
Trying on make up
Trying on female clothes
Removing body hair
Using feminine body language
All of these things felt incredibly natural and helped me understand that, yes, I am transgender. I started HRT this week and I was really excited when I could start. I’ve been denying this part of my identity for decades and finally being able to embrace that part of myself feels really euphoric.
I don’t know how this feels for you, a low sex drive could have many causes, but reading through the replies on this post and actively experimenting really helped me narrow this down. One of the kind people here recommended genderdysphoria.fyi/en/, which was also a great resource.
