I was certainly attractive presenting male and understand that thinking and worry... however, i found i was the one that found myself the most unattractive. It was my own image in the mirror i battled more than others perceptions of me.

Transition was a miracle in easing that, softening the image i saw. It was pretty incredible, the further i transition the more the dysphoria transfers from self perception to the perception of others as far as being seen as how you see yourself.

I think you will find being attractive is outweighed by a desire to just be happy. Transition involves a lot of self acceptance. All of the things you mentioned are obstacles but not impassable. The big 3 are extremely common and can be fixed over the course of time with transition. Everyone needs voice training, i had to get hair transplants myself, and body hair? I am italian... yeah. It sucks. But hormones really do lessen it!

I had extreme dysphoria over all of those things, however my hairline improved, my voice improved with practice, my body hair lessened, my shoulders arms and legs got smaller as the muscles reduced, laser wiped out my facial hair. If i could do it all again i would just do it even sooner.

I would just consider it long and hard otherwise you may very well only delay the inevitable with more time of regret added

Good luck!
