curved and upward penis

when i was in middle school i noticed a round pimple like thing on my shaft and the pimple like thing was painful to touch, and it was hard to the touch. when i quezzed it (and it hurt when i did that) puss came out of it but the thing was still hard though. after many years it has mostly gone away but some is still there. now when i get an erection my penis has a slight curvature, and my penis goes upward when erect( is that normal?). In middle school i had my first physical and the doctor noticed it while examing my penis, but he said nothing, no questions. Im due for my annual physical, but not sure how to bring the concern up. what do think this is?
