I'm 14 years old & I have a hard cord like lump on the left side of my penis. It's always hard, no matter if I'm flaccid or erect. However, it's less noticeable when I'm erect. Pushing and massaging the lump makes the lump go away, but only temporarily. I think it was caused from masturbating too much, so I've been taken a break for about a week and a half. I plan to continue for at least a month. Please help I have no idea what it could be or what I should do besides just wait.
