I had unprotected sex 5 days ago and now I am very worried i have contracted something. The tip of my penis has constantly been in very mild pain, almost like a tingly burning sensation. Nothing that is super painful but it is something that is noticeable all day long. I frequently need to urinate and for the most part I feel like I need to urinate all the time. Today was the first time I felt pain between my scrotum and anus. It was mild as well but lasted for several hours. This subsided and now the tip of my penis burns/tingles. Any insight into what this may be would be greatly appreciated!
