Whenever I go to toilet to pee, I always roll my skin down and then shake my dick. I then wipe with a tissue until it is dry because I don’t like any pee on my boxers.
Someone mentioned that tissue on my penis could irritate it, is this correct?
That is true. I used to do that when I experienced some discharge and my urologist said to stop that immediately. All tissues except some for gental care contain parfumes or other additives to make them softer and nice smelling.
Wiping your gland dry with a paper wipe can cause moderate to severe irritations to the tip of the head and the meatus, so I suggest that you stop that immediately.
If you want to wipe out all the urine, that is a great hygiene practice, so please wash it with warm water and damp it dry with a soft cotton cloth. Make sure that the cloth is washed with a soft detergent or sanitized with H2O2 every few days.
