I was just finishing my session with some hot water in the shower and I accidentally dropped some very hot water on my glans and foreskin, it was just a few drops, literally.
There are no blisters or anything noticeable (hard to say for the glans because of skin texture and colour there), but the foreskin was already sensitive due to recent irritation and it “felt” the hot water.
I put my penis in cold water for ten minutes and then applied cream used against first degree burns. I will apply the them cream until Tuesday and hope to resume PE then. There is no pain, perhaps some minor irritation on foreskin. I had the same years ago, two days before a date and I managed without problems then, so I won’t wait more than two days before using the tool.
Hope it helps if someone goes through the same. Input/advice is also welcome.
