I am 26 years virgin guy.I have never involved any vaginal/anal/oral or any other intercourse throughout my life.I was busy with that days so I just overlook any smegma related issue.I have been feeling pain around glans penis and the ring since 2012. I thought there might be a stone inside my penis.So, I decided to go to a doctor.Last 15days I've been suffering with fever and cough.The doctor said a thick cheese like smegma is around the ring almost 8-10years .the doctor said you have been suffering PENILE CANDIDIASIS along with thrush on tongue.after cleaning smemga, he prescribed azithromycin (azimax 500) tablets, clotrimazole cream for penis-application, metronidazole cream for tongue application.ALMOST EVERYTHING IS FINE, NOW I HAVE NOTICED A PATCH OR RED SPOT(NO PAIN OR INFLAMMATION) ON THE GLANS PENIS TOWARDS TO THE RING.WHETHER IT IS INDICATED ANY STI/CANCER/HIV DISEASE? provided, i'm uncircumcised. I'm habituated with masturbation and never touch even any genital of any person. I feel worried. A quick answer would be appreciated.
