Please seek immediate medical attention. The appearance of black skin on your penis is a serious warning sign that could indicate tissue death (necrosis), restricted blood flow, or a severe infection. Do not apply any over-the-counter ointments or medicines, as they may worsen the condition or delay an accurate diagnosis. A doctor needs to examine this in person right away to prevent permanent damage or serious complications. Please go to an urgent care clinic or emergency room immediately.

Red spots and skin tearing after intercourse can be caused by friction, lack of lubrication, yeast infections, or sexually transmitted infections (STIs). To help the skin heal, keep the area clean and dry, temporarily avoid sexual activity, and avoid harsh, scented soaps. While over-the-counter barrier ointments or mild antifungal creams may help, it is highly recommended to consult a doctor or urologist before applying any medication. They can accurately diagnose the underlying cause and prescribe the correct treatment, such as a specific prescription steroid or antimicrobial ointment, to prevent further irritation or infection.

To soothe your sunburn and reduce inflammation, apply pure aloe vera gel or a mild 1% hydrocortisone cream to the affected areas. A gentle, fragrance-free moisturizer applied while the skin is damp also helps lock in hydration. For discomfort and swelling, over-the-counter oral pain relievers like ibuprofen or acetaminophen are highly effective. Please avoid topical products containing benzocaine, as they can cause skin irritation. Keep yourself well-hydrated, apply cool damp compresses, and avoid further sun exposure. If you develop severe blistering, fever, or dizziness, please seek medical attention.

Mango sap causes a temporary allergic reaction that can leave dark marks. To relieve itching and inflammation, apply a mild over-the-counter hydrocortisone cream (1%) twice daily for a few days, and take an oral antihistamine like cetirizine if needed. Once the irritation subsides, you can address the dark marks, which are temporary. The most important step is applying a broad-spectrum sunscreen daily, as sun exposure darkens these spots. To help them fade faster, you can use topical creams containing niacinamide, azelaic acid, or vitamin C. Rest assured, these marks will fade over time. See a dermatologist if the reaction is severe.
