ok on the left side of my penis there is a red bump and it is kind of hard not really but when i get a boner it gets real hard and dark red. after i beat off it stayed red but softened up. any idea what it oculd be? the bump is a little less ruond then my pinky and doesnt stick out much. ive never had sex, got a handy or a bj, but ive touched the top of a vagina and then i whacked off like 30-40 minutes later.
