If it is in the movie, it is acceptable, that is as good as real life, not reel life. You join voluntarily to exploit movie world with your beauty and charm, and do all acts including nuptials. Is it in real terms or reel terms? Any how it is a physical act, not a robotic act. You gyrate half-naked in the movie, is it real or reel or robotic. Became a fashion to rewrite the story of the movie after duly establishing stardom.
