Sexual Revolution or Drunk In Love

Why is it not permissible for performers such as Beyoncé and Jay-Z to copulate on television. What with beating the box and eating the cake, how could it be inappropriate since they're rich and famous beautiful people.  The lyrics say he can't wait long enough to remove her panties, so he just pushes them aside.  He should go ahead right on stage. They could set a precedent with something heretofore unseen at the Grammys........  Though some years ago, in the wee hours of morning TV,  Cable TV did show such an act, but the participants were members of a convention where they all pretended to be horses---yes, they did (it).
