Friends at Twilight1999

Captured by a brood of vampires at an old castle, a man finds himself in the midst of the vampires' dinner party and orgy (for both straight and gay). The vampire leader (Joe Marzano) gives a long speech, quoting from Oscar Wilde, and it's the same speech delivered in Marzano's Venus In Furs (1967). As the orgy evolves into a fandango of psychedelic imagery, the captured man turns to stone.
