i have a bump on the head (corona) of my penis. it does not itch, hurt. looks clear but at times will have like a blue dot. sometimes you can't even notice it. i've always had a bump there for as long as i can remember but am worried it's something worse. i'm 25, 6'3", 180, male, and have been sexually active with 5 women in the last 5 years (all unprotected but clean). healthy medical history -- two hernias -- that's it. very active runner, good shape. do not sleep around with strangers.
