I had unprotected sex with a girl at the beginning of 2016, after which I started experiencing swollen foreskin, redness on glans, burning and itchy around the glans. I got tested for STI (Chlamydia, Gonorrhoea and Syphilis), the results were all negative. The doctor said it's yeast infection and prescribed Clotrimaderm cream which I used for 3 weeks. The symptoms got better but not completely. I went back and doctor said it could be bacterial Balanitis and give me Flagyl (metronidazole). But after 2 months and trying another cream Lamisal and oral pill (Diflucan), i can still feel and burning sensation around the glans from time to time. I had unprotected sex with a girl in June, she developed yeast infection and bacterial infection, she's sure she got it from me as she had not had sex in a year. I used anti fungal creams for 2 more months, but I can still feel burning sensation now and also notice a fishy smell from my glans. Is it a chronic yeast infection or it could be bacterial?
