This poor chap was injured by hitting his skull on the headboard of the bed during sex but we can see that head injuries do not necessarily impede a man's sexual abilities, especially when he's got an angel of mercy such as Angelique bringing him back to health. The term "Nil By Mouth" on the sign is the instruction to a caregiver to not give the patient anything to eat or drink unless directed by a physician. It means that the patient can't swallow. He can lick boobs however.
