The reason why I said "does not prohibit" is because usually it works as if it is not specifically prohibited by the law, then they treat it as allowed.
Based on my experience, I can list some of the states which I went.
Ohio - not allowed. Utah - not allowed. (Even Lap dance is prohibited when they are selling alcohol or the stripper is nude.) New York - Not allowed. Oregon - Not allowed. Georgia - Not prohibited. (But depends on clubs I guess?) Indiana - Not prohibited. (But the strippers have to wear pasties and panty.)
I am not really sure with other states. Would you share your experience?


I think you need to define exactly the meaning of "two way full contact to stripper" so we are all working with a common understanding. A lot of what goes on in a club may depend on whether alcohol is served, whether the stripper is fully nude and whether "home rule" takes precedent. That is, the local municipality can have its own rules which can be more restrictive than the state law.
In general, in New York a stripper can be fully nude on stage and for lap dances if the club does not serve alcohol. For a club that does not serve alcohol, a customer cannot touch when the stripper is on stage, but it's O.K. to touch, with permission, during a fully nude lap dance, except touching her private areas.
Years ago, I was at a club in the Hudson Valley and a fully nude dancer handed out paint brushes. The customers could buy a paint brush and "paint" her in any area using some paint while she was fully nude on stage. Apparently, a "paint brush" is not touching!
The owner of another club that didn't serve alcohol told me I could "tip" while the fully nude dancer is on stage, but no touching. And tipping is strictly prohibited when the dancer is off stage or when the dancer does a lap dance. He wanted to immediately know if any dancer should ask for a tip or suggest that you will get a hotter dance for a tip. It has to do with what the local municipality considers to be prostitution.
The nuances depending on locality can make a big difference in your experience.
