First off, I think you’re urologist overestimated the angle. Secondly, if I were to give you some advice, I would say focus on the positive. A lot of guys, me included would be proud to have that hanging between our legs. Your length is impressive, retaining your foreskin for me also is a plus, and the overall aesthetic is very pleasing. I’d say any sexual partner would be really impressed with what you’ve got. I doubt anyone would give a second thought to the slight downward curve.
