I was born with Hypospadias where the urethra doesn't exit exactly at the tip of the penis. It's genetic and my dad had it too. The docs can tell at birth you have it, but can't tell how severe for a few years until the penis develops. My dad needed surgery to 'fix' his, so the docs said leave the foreskin so that a natural skin graft would be available if needed. Thankfully my case is very mild - instead of being centered in my 'slit', the opening is at the bottom, kinda where the frenulum meets the head. If you notice in my precum vid the hole is at the bottom end of the slit. If I pee or cum hard it shoots out through the slit, but any dribbling just comes out the bottom end. Makes dual stream piss pretty common actually. Anyway, being 5 years old by this time, the parents decided I was too old to have a voluntary surgery like that.
