I know nothing on the expanding subject but i do know that after you go through the clitoris release and your on T for about a year,it grows and expands on its own as if your hitting puberty as a male,this is why i plan to have the release THEN finish anything else after i know i have grown my full possible length.But there are *so i read* surgery's you can have that allows to gain more mass and length tho im assuming this is a seperate surgery aside from everything else,how they do it i have no idea but i heard some trans men going as far as 8 inchs in length,one guy asked for 11 O_O and got it too!! of course he later had it reduced but hey.never know what they will come up with
