I was just about to add a transgender flag overlay to my Facebook profile picture, but then I started thinking about this again. Am I really trans? Would it be okay to add the flag, or would I basically be an impostor? After all, I have the lifestyle of a fetishistic crossdresser, and I'm not gonna change it anytime soon. Am I trans? It sure doesn't feel like it, but my god, I want to be a woman so badly.
Maybe it is best to experiment a little instead of asking yourself if you are allowed to do something all the time.
Personally I see someone who is questioning as part of the trans community until the answer you arrive at is "I am cis and ok with it'.
Maybe you could also turn it around. Instead of asking yourself if your feelings qualify you to be trans do you think they qualify you to join the cis club?
I highly doubt any cis person relates much to what you wrote while I sit here relating to many of your struggles as a trans woman
