Thanks for your answers. Maybe I should reconsider my plans 
My main reason to want brain rewiring is. To be more calm (i have tried meditation, etc) it is difficult for me to relax 100% To reduce my mastrubation and sex drive. Hopefully make it easier for me to accept my transgender side. And of course the physical aspects. Get a nicer and smoother skin. Less muscle tone. Reduce body and facial hair and increase my normal hair.
I train hard 3-4 times a week and on a diet. So there is not much body fat left
