I'm new, and not sure where to say this, but more than ten years ago, I rented vhs tapes from a local video store porn section, and there were several scenes of gay European men playing ping pong. it was not a natural setting, but it was a reoccurring thing, with many different young guys. I didn't get it at the time, but wanted to share this, as it must be a popular thing. The series is called powerboys, and was available to rent at video stores.
