Hello dear, Understand your concern. I think it is due to rough sex. Other causes are may be- 1. Hygiene problem: If you not wash penis area, segma that is deposited under fore skin irritate penile area and produce reaction 2. Balanitis: inflammation of the penis, caused by poor hygiene, especially insufficient washing under the foreskin area. Thrush, psoriasis, skin sensitivity or allergy to a product used on the penis (such as soap or lubrication) 3. overuse - as in too frequent, too long or too rough sexual activity 4. Fungal infection: in warm environment. Take following advice: - use safer sex techniques - Use condoms and lubricants while sex - Insert penis in vagina after its get fully wet - Be relax - Do regular exercise 1.Change to a simple, unperfumed soap. 2.Alternatively, buy ‘aqueous cream’ from a pharmacy and use it as body-wash cream (i.e. apply a small amount and rinse off). 3. Put two handfuls of salt in the bath, but no other additives 4. Do not use ‘biological’ or ‘enzyme’ powders when washing your underpants 5. Showering after a workout, changing underwear, using a clean towel to dry off with and not redressing until the area is completely dry 6. Use ormulated penis vitamin formula- Man 1 Man Oil-contain: with vitamins, minerals and shea butter- it moisturizes the skin and prevents flaking or cracked skin while revitalizing and enhancing the sensitivity of the penis 7. Apply anti fungal clotrimazole cream if severe or not resolved.
