(b) “Sexual penetration” means entry into the dead human body's genital opening, anal opening, or mouth by the actor's penis, finger, tongue, or other object, or the touching of the dead human body's genital opening or organs by the actor's mouth or tongue. Sexual penetration may also be entry by any part of the actor's body or some object into the genital or anal opening of the dead human body. Any entry, no matter how slight, is sexual penetration. Sexual penetration occurs whether or not the sexual act was completed or whether or not semen was ejaculated.
