My understanding is that "bottom surgery" is actually much less common than most non-trans people assume.
Right. Not least because, F-to-M surgery is kind of... not really perfected. I gather M-to-F is much further along, but I don't know how it does on the "retain sensation" scale. (And anyway, in general, who takes a sharp knife to the crotch in the absence of necessity? Besides all those scary people who want designer cooters on Dr. 90210?)
