This afternoon I had an examination by the surgeon. Despite the lack of raw material, there's enough for the operation not to be a problem.
Thanks goodness I was never circumcised - or some creativity would have been needed.
Guven that I'm unlikely to ever have sex, I opted for an average depth, rather than one more useful for a well-endowed boyfriend. This means I can get away with no unsightly skin grafts. But I'm told 15cm should be doable, maybe more if I work at dilation a bit.
And that evening, while having dinner in a street bistro with a number of other patients and their partners, I got to feed and photograph an elephant. Pics tomorrow when I have a link capable of uploading jpeg files.
