Hello, You seem to have allergic or irritant rash on your penis. A few causes are genital psoriasis, sexually transmitted infections, balanitis either bacterial or fungal, eczema, allergic reaction to condoms, lichen sclerosis, friction, Peyronie s disease, and urinary tract infection. Treatment depends upon the cause. You may be able to relieve some irritation at home using any of the following methods. Moisturizers or anti-itch creams. Look for creams made especially for the penis area. These are less likely to contain harsh ingredients. Salt baths. Taking a salt bath can help with itching and discomfort. Cool compresses. An ice pack or another cool compress can relieve irritation. Wrap it in a cloth first before applying to your skin to avoid over-chilling the area. Abstaining from sex. Avoiding sexual intercourse and other activities that may aggravate the skin around your penis is a good idea until your symptoms improve. If your condition doesn t improve, you need to consult a physician for further evaluation. Take care. Hope I have answered your question. Let me know if I can assist you further.
