Is it normal for an uncircumcised penis corona— the back of the penis head gland — to smell bad? Its also sore and irritated but it does not hurt at all. Very rarely it itches. I don't see any smegma because I wash my penis head every time I shower. However if I pull back after a long day, and touch my corona, my fingers smell bad and the head is shiny with clear discharge from the corona. Is this normal? Could it be an STI?
