Yes, I know this is a weird what if, but if you were to go blind, would you still crossdress? Think about it. Men are very visually oriented, and you would not know how you look.
Plus all the work it takes. The only aspect of CDING would then be the feel, and you would pretty much be forced out of the closet. You would need help selecting and buying clothes, washing, etc. Your life would be much more difficult. Would you even bother?
