Hello Dr, I have serious problem. Its now 13 years with this problem. I have done the HIV test several times and the results are negative. I was given STI treatment, the problem still exist. My pens shaft is always itching from inside towards the of the penis. Sometimes the foreskin itches as well. I m always visiting the bathroom to wash my self. There is some thick fluid (like diluted sperms) that is discharged. I m sure the common STI drugs they don t work anymore on my body. I am residing in South Africa. Please Dr help.
