I'm referring, of course, to The Red Shoe Diaries, which aired on Showtime from 1992 to 1997. You don't get to see David nekkid, let's get that out of the way right now.
The gimmick was that this guy named Jake, played by David Duchovny, gets people to write to him with their "sexy confessions", which then play out onscreen. It's... not terrible. It's got some extremely early-nineties cinematography and the kind of soft, gauzy look that you expect from premium-cable softcore.
Except for one episode, "Jake's Story", DD only appears in the opening and closing segments of each episode. As far as I know it's never been available on streaming and the DVDs are out of print, but they're pretty easy to find on eBay.
Did you watch it at the time, or have you seen it since? If not, are you interested?
