Replying to Cups for urban?

I recently re-watched an older video NS posted on FB of this dude who nutted himself on a rail. The guy literally fucked his shit up so bad my balls sucked up inside me just watching. Got me thinking, has anyone ever worn a cup while doing urban? or any skiing at that. I have never worn a cup outside of when I played lacrosse in high school but it might be a good way to keep yourself from folding your dick in half when it meets metal.
