text: why is there a purple dot on my penis? there is a small purple dot close to the hole on the penis that you piss through...about 2 months ago i was taking as shower and the really fast water coming out hit that spot on the inside of the penis skin and it freaking hurt...i think its not as purple as before but im not sure and i would really want suggestions since i'm getting kind of worried...the dot is small like the size of a small crumb go see the doctor. if you are worried about asking a parent to take you to the doc, walk into public health. a little embarassment now is much better than having something really be a problem and ignoring it.
