The best time to start to transform a male body into a female body is at puberty, 12 or 13. That is when your hormones start shaping your body to become that of a man or woman. At that age if you stop the testorine with blockers and start taking as much estrogen that is safe you're body will definitely grow female. For those that would love to have a nice, curvy female body could you have with stood the pressures and criticism of fellow students, adults and anything else that was alive to have undergone hormone therapy at that age and continued through high school? We all know how cruel teens can be. By the time you were 15 or 16 you would have a nice set of boobs that couldn't be hidden as well as all the other curvy and protruding female body parts. To have suppressed these feelings and waited until graduation and freedom from school to start hormone replacement therapy would have netted you far less results. You would be starting from zero trying to remake an already formed male body. Words such as isolation, shuned, no friends, loneleness, made fun of, etc. come to mine. Would it have been worth it, could you have handled it?
