Goodday doctor, I am writing on behalf of my husband, he has been having sores on his penile shaft, around the base of the penis and on the scrotun for about 11years now, he has been having the sores since he was a virgin and I am the only sexual partner he ever had. He has been treated with antibiotics about twice and also for yeast infection but the sores are still persistent, pls we would like to know what could be the cause and a probable solution. Thank you
