As a competitive sport, wrestling is completely fake. Vince McMahon admitted that in the 80's. But I enjoy watching The Wizard of Oz and it's fake too. The strength, stamina, and acrobatic skill of the wrestlers is definitely real. It's amazing the way those guys get thrown out of the ring, hit with chairs and other things that would seriously injure most of us. Yet, they go back to the ring time and time again.
Unfortunately, I haven't seen any of the "spankings" that have popped up on some of the wrestling shows and can't attest to their authenticity. The stills I saw of Major Gunns looked to me like her buttcheeks were covered with rouge, but I don't know how they could've done that without getting some on her costume. Endart said he though that one was real even though some of the other's looked fake, and I'll go along with that.
