Swimming naked is called "skinny dipping". I don't know what you'd call sleeping naked though. James Bond never wears pyjamas. Neither, if Homer Simspon is to be believed, did Thomas Eddison.
I have tried it a couple of times. The problem I find though is that I wrap myself up in the bedclothes to compensate and then wake up covered in sweat - and smelling! It makes the bedclothes damp and smelly too.
Well this morning as I got up and did a few household chores I listened to the first scene of
Das Rheingold. It's simply glorious. It's a very neat little parable in an of itself, about sexuality, virginity and the foolishness of inexperience, and the desire that old age and ugliness has for youth, beauty and sex.
Crucially, the Rhinemaidens - being maidens - confuse love and lust. They imagine that the Rhine gold is perfectly safe because they cannot imagine that Alberich, a creature of such dark and potent sexuality, could ever renounce love, which he must do if he is to unlock the gold's power and wield the Ring. It is their encouragement and then rejection of Alberich, and his subsequent renunciation of love, enabling him to steal the gold and forge the Ring, that sets the tragedy of the whole cycle in motion.
Thematically it's actually a remarkably subtle start for a story whose overriding theme is the conflict between love and freedom (i.e. "free love", incest not excluded!) and authority and duty (albeit the essentially arbitrary authority of Wotan, whose laws are burdensome even to himself).
The piccie above is one of Arthur Rackham's. Obviously the Rhinemaidens are not normally naked on stage, and to date no one's actually found a way to make them actually swim either. But that doesn't mean the audience will necessarily be spared
silliness of other kinds.
