I stumbled upon this article that mentions a program from the 90's: HBO's Real Sex.

The article only features one photo. I think it will be difficult to find the actual show. Maybe it's one of those things that will pop up later. But from another article the show has been removed from HBO. I don't have HBO subscription so I haven't checked.
