The question was about paying Dr. Kimmel for removal of the scrotum at the same time as the castration.
My own OPINION, based on my experience and from what I have read of other accounts, is that it might be better to postpone the scrotal removal to a later time.
I do think it is better to simply be castrated and let the scrotum heal thoroughly. For one thing, you will have several months with an empty scrotum, and may find it acceptable. If not, the removal of the empty scrotum will be a lot less stressful on the body then having both testicles and scrotum removed at the same time.
