For treating prickly heat in the genital area, the following methods can be used.
Firstly, keep the area clean and dry. Wash the area gently with mild, unscented soap and warm water, and then pat it dry with a clean towel. Avoid using rough materials that may irritate the skin.
Secondly, wear loose - fitting and breathable underwear, preferably made of cotton. This allows air to circulate and helps to reduce sweating and friction.
Applying a thin layer of calamine lotion to the affected area can also provide relief. It can soothe the itchiness and inflammation. However, be careful not to get it into the genitals. If the condition doesn't improve or gets worse, such as with signs of infection like redness, swelling, or pain, it's advisable to consult a doctor for further treatment.
