Hello, Clotrimazole (brand name Lotrimin) is an antifungal medication commonly used in the treatment of fungal infections. In your case, it may be an STD (sexually transmitted disease). Chlamydia is a sexually transmitted disease sometimes causing painful urination, penile discharge and more. Gonorrhea is a sexually transmitted disease and can cause painful urination and penile discharge. In cases of infection, a diagnosis can be made by taking a urine sample or urethral swab, and can usually be cleared by a course of antibiotics. In the case of a sexually transmitted infection, it is recommended that sexual partners are also treated. Antibiotic treatment will be helpful for you. Continue applying antifungal ointment. The most secure way of prevention is definitely sustaining from sexual intercourse. Another option is to be in a long-term monogamous relationship with an uninfected partner. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Iven Romic Rommstein, General Surgeon
