I noticed the opening of my penis is abnormally red, and sensitive to touch or any rubbing of my underwear. The cotton from my undead or what ever I m wearing sticks to the opening, at first it did not hurt, after a match of soccer yesterday the area has been burning, like a rash would, I thought that I might have just irritated it, but now I ve noticed some white/ yellowish discharge . I have not been with any new girls recently. What do u think it might be? Uti?
