Starting Feminization

Hi there! I recently found a Dom who is wanting to feminize me, I have always been into the idea of forced feminization and am most eager to do this process with him. I was wondering if you could give us some tips or ideas on how to help with this process. He is wanting to shrink my 6" cock into an inverted clit (prior to having me get surgery) and wants me to grow boobs and get a more feminine figure. What can we do to start this!
