For last few weeks I've started to experience burning sensation in the penis after I masturbate. If I drink lot of water and urinate after some time, only then it goes away. About 3 months ago, I had sex with a woman I met. I had used protection. This problem started only about 1 month ago. I had also used Dapoxetine 30mg since I have the problem of premature ejaculation. I don't know what is causing this problem. It might be just infection, or
STD, or even prostate cancer. I'm not sure what it is. Can you please help me out?
