Several months ago, I felt a sensation in my penis that resembled a grit being lodged near the head. Was not sure what it was but it subsided after several days. But, it has continued to flare up more frequently now and it feels like something is lodged in the urinary tract???? I have no issues with urination and there are no signs of STD s, so, is it possible that I have a stone? I don t want to have sex because of the pain. The last time that I had sex with my girlfriend, it felt like something ripped .
