Is it normal for a man and his wife to run naked in a field?

I've noticed such perverts like to take their clothes off and don't tell me it's just nothing being naked because it's not, adults have sexual intentions behind nakedness unless of course it's a bath, posing, shower, public bath, public shower, or change room or trying to be funny or shock you, naked adults aren't innocent, they show off and often are silly about it.
An adult naked isn't just standing there naked, they're standing there to look so exposed it's external, when a man and his wife run in a field naked it's a symbol of sexual love for the wife and husband, what adults get away with is posing naked for a photo or drawing or painting, which makes it legal, that doesn't make it right, a naked cop is probably one off duty in the shower, is that normal?
