Six weeks postop with Suporn here.... very satisfied with my whole hole experience.

Depth was just over 7" a week postop. I haven't been knocking myself out to keep that, so now it is around 6.4 inches, which is ample. I have experienced no problems yet, although yes, the many stitches do make it a bit painful. I just can't imagine how another surgeon would do it with less, though, either in one stage or spread out over two.... I'm just getting over it all at once.
As for how easy it is for the skin to tear, like during sex etc? Well, try to push your forefinger into the web of skin at the base of your thumb.... skin is EXTREMELY tough. It would be tough to break with a knitting needle, let alone a penis, lol.
Sensitivity, since most of the stitches in that area have fallen out, is amazing.... the feelings i'm getting from down there reallllly make me look forward to another month down the road! And yes, Suporn uses the rest of the glans to create a second sensate orgasmic area (called the chonburi organ I believe; I call it my second clit, but I get flamed on this site for saying that.... if I can orgasm from it, it's a clit. Period.
To each their own, but while there, there were 20+ girls postop staying at the hotel with us, almost all looking really happy. The walls of the clinic have heaps of grateful thank you cards pinned up, a hundred or two easy. I'm adding mine as soon as I've written it and mailed it. Lastly, he does offer free lifetime revisions if you need one, for cosmetic or functional reasons.
