Hi B, as long as you are taking good care of your personal hygiene that is all that matters. So, for example if you are able to take a shower after your first toilet visit of the day that would be good.
In terms of penile skin generally, most body cleansers including soap and shower gel can be harmful to penile skin and cause excessive dryness. So when washing or showering yourself do not apply soap directly to your penis, use the water only and the inside of your hand to rub your penile skin clean, particularly around the tip of your penis. Then, you must make sure all of the penis is completely dry, as any moisture can also cause problems.
What can also help is if you get yourself some liquid coconut oil and apply a thin coat to your entire penile skin every other day. The best time to apply this is after you have completely dried yourself after taking a shower.
