== Erection == 

 Is the koteka shaped in such a way as to accomodate erection? Or would it be uncomfortable (perhaps even dangerous or fracture-inducing) if you had an erection while wearing one? The one in the picture looks curved, which would be fine if you stuffed your flaccid penis into it, but if you got an erection it would be very, very painful unless your penis was naturally upward-curved when erect (as some penises are). Perhaps over time the penis's shape changes to fit the shape of the koteka, making this a form of body modification? I don't know for sure but I'm just curious.
