Well, I know that some countries are mor restrictive in this case.

But I wanted to tell you, that this forum is international and if somebody wants to know about nude bathing beaches in USA, he should tell us.
If he simply asks about nude swimming ( or bathing?) beaches, he should write his questions down that way.

Lots of states allow nude swimming and sunbathing (exspecially the scandinavian states and the states around the baltic sea).
As long as the beaches are not declared as textil beaches (by trafficsigns) they are free for textil and nude swimmers.
Most times it is normal that nudes and textils are at the beaches at the same times and nobody cares.

I please you, to understand my first message in this way.
