I have noticed a couple of things in the last few months and I wanted to seek clarification. Firstly, sometimes (Rare: once in a month sometimes more) when I pee, I get sharp pain below my left rib cage. Then my right testicle sometimes has a slight pain when I ejaculate and also sometimes my Penile tract burns after ejaculation. There is also a powder like substance under the head of my penis every morning. I keep excellent hygene and I wash myself frequently. I am worried.
