I didnt have one till last year

*edited before ppl get confused*

Born with one, had a hernia.. docs got rid of that and my bellybutton left me with a 3- 4 inch scar instead.. had a bellybutton made out of the scar last year

1st time i ever touched it i felt sick, had never felt inside my bellybutton before (obvisouly) and it felt really weird
