Hello, If you are not accustomed to oral sex & had prolonged rough oral, it could be due to penile friction. The more the penis is sucked the more it is depleted of its natural fluid and oil. It can leave the penile skin dry, rough & sore. When oral sex is done by a partner who is ill, may pass on infection. Condoms may help. Avoid oral sex for an hour if the partner had hot, spicy food. Its suggested to use mouth wash, and to wait a decent amount of time. If spices linger on the tongue & throat, it can make an extremely hot penile skin. Avoid sex & masturbation for a couple of days. Wear soft cotton clothes. Take care of your hygiene. Apply vitamin E based cream which can soothe the irritated skin. You can also apply cream containing L-carnitine, a neuroprotective ingredient, can help restore lost sensitivity. Soframycin ointment applied in the affected area will also work effectively. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Nupur K, General & Family Physician
