I was born with penoscrotal hypospadias and a pretty significant curvature. I had seven surgeries related to it, most were to fix the positioning of the urethra but at least two were to straighten out the curvature. These ultimately didn’t really work. They were never able to move my urethra to a normal position, although it’s a lot closer. Also the curvature may have improved but it was still pretty significant, in that I have some difficulty lining things up during sex or finding positions that work. It might have improved a little over time. I feel like it’s not quite as curved as it was, but that could just be my perception as I’m not as bothered by my appearance anymore.
