Could it be bad my penis touches my belly button when erect and i'm sitting down?

If U have epispadias: Congetital condition with urinary opening located on upper surface of penis which is curved upwards. Epispadiac penis is usually very short. Combined with curvature makes sexual penetration difficult. Upward curve can be due to peyronie's disease, where there is a bone-like plaque underskin on upper side of penis. Might also have a severe congenital dorsal curvature. Suggest cosult a urologist.
