They already had this idea about 10 years ago. Admittedly they didn't do it in a box in the studio, but they took couples who wanted to experiment with sex (IE the woman being the 'Top'....) taught them about it, and then the couples would make a vlog right after it and then do a proper interview the next day. Nothing new.
Can't remember what it's called but they still air it on 4Music around midnight occasionally.
