First I do not have access to the entire legal code of every location in the USA but a good starting point would be the areas where one can be charges with public indescency/intoxication.

But I hope that most logical thinking people can say that being behind 4 walls, a roof, a closed door, and closed windows constitute a private area. If your own home is not a private are then what?

There is a MAJOR step from g-string to public sex. You are using the same argument that the pro-abortion / anti-gun groups use.

A strip club does have an effect on the surronding area. That is why they can be regulated by the local goverment.

Well, the in-practise definition of adequately covering private parts started with full size panties and migrated down to a g-string.

Likewise courts have been pretty arbritary with regard to what constitutes a private sub-space within a public space. The trend has been liberal -- allowing more claims against prosecuting on the basis that there was some expectation of privacy even in public areas. You argue using the most secure and easy to define private space -- in practise there are many more private spaces much less secure and easy-to-agree on than a bedroom in your own house.
