Here is a link to a popular guide for Suporn, written by a woman who had SRS done by him. She wrote that you need 3 months to recover before feeling mostly normal again:

You're probably aware that the recovery period for the skin graft technique is much longer than that for traditional penile inversion SRS. I had SRS with Chettawut, who uses a similar procedure as Suporn. Based on my own experience, I think 3 months is about right.
