Sorry for your upset too Stan. I don't support the OP's wish to be circumcised. Construe it as you wish. It is a bad idea.
This is the kind of attitude that sickens me. He is now making the choice why can't you just leave him alone. This isnt one of those babies you are trying to protect. This is the same thing the mod was telling you about last week. It's clear you are just against circumcision and not just RIC.
Anyways to the OP:
1. Let him give you the pain meds before the circumcision so that when its time to go you can take it shortly after
2. Get some dark briefs. As tight as comfortably possible. I would say go to wal-mart before hand and get some. Briefs...not trunks or boxer briefs, they tend to stretch more in the pouch and thats where you will need the support.
3. While in WalMart get some Epson salt. When taking off the bandage this will help in the soaking.
4. Listen to the doctor.
Additionally in looking at your condition I think you are making the right decision. You should definitely put up post operative pics.
