>As I understand it the "sex tourism" laws cover behaviour that is not legal in the US, but is legal in some other country. Well, in the best example, it is a bit complicated. Take age of consent. Within a state, state law rules. Between states, federal law rules. In most cases, federal law is stricter than state law. So it would be an action that would be legal in the state you were a resident of, but not in another state. Also a counter example. Prostitution is illegal in most states, but it is, to a limited extent, legal for an American to engage in such abroad (much like it is legal for residents of Texas to go to Nevada). In short, I believe there are laws that do what I describe and laws that do what you describe. (Note I'm not a lawyer and the laws have changed a bit since I last read them.)
