Having a crimson, parched, and flaky penis top can be unpleasant, however, there are only a few things to take into account. After masturbation or a hot bath, it’s typical to get marginally crimson. This could be due to irritation from soaps or lotions, a fungal infection, or even sensitivity to certain fabrics. To help, try using gentle soaps, avoiding tight clothes, and keeping the area dry. If the symptoms persist, seek advice from a dermatologist who can provide the right treatment.
