I think that just gets really creative when it comes down to seeing your favorite female superstar and male superstar. I know we’re a little bit sensitive with a man putting his hands on a woman so we’re trying to stay away from that, but overall, just the beautiful sport of professional wrestling in its full capacity is so beautiful to watch man. You enjoy it, I enjoy it as a wrestler. I can only imagine how the fans enjoy it as fans. I tell you what, I think I would probably go with Asuka," the WWE legend said.
