The most important thing is that you clean your dick regularly under the foreskin. Otherwise, no special treatment is necessary! Your intimate area, especially your dick, does not need to be washed more often than your other body parts, for example.

Excessive washing unnecessarily disturbs the natural bacterial flora and thus creates a basis for fungi, bacteria and inflammation. Strongly perfumed shower gels can sometimes intensify this effect. It is therefore best to use unscented detergents for your dick. Clear water is best.
