I think the biggest lesson to pass on to others is that dilation does get painful at certain times, and that backing down dilator size will not cure the pain, only lead to greater issues regaining width. I spoke on this before, where I went through a period where it hurt like hell getting in the number three dilator, it took forever to get it in, and I bled every time. I worked through it, it took several weeks, but now the pain is gone and the bleeding is as well. The biggest mistake a person can make, in my opinion, is to back down sizes in an attempt to avoid pain. What works for me, I dilate with all three sizes every time. I start with the smallest for 10 minutes to keep depth, move to number 2 for 5 minutes to loosen things up a bit for number three, and then move to number three for 10 minutes. This has worked very well for me, and I have not lost any depth since surgery.
I never heard of inversion being more prone to prolapse than skin grafts. It would seem to me that a graft is a graft, and essentially inversion is just another version of a skin graft, just without the additional scaring of harvesting skin from other places. I have never really thought of it as the penile tissue becoming the vaginal wall tissue. It's really just skin, and over time the nature of that skin changes as it adapt to it's new use. I'm curious though how sensation differs between grafts and inversion?
