This famous italian Spaghetti Western actor
http://www.imdb.com/name/nm0049673/
is featured in a 1981 movie called Pensieri Morbosi (dir. Jacques Regis).
Also featured in the movie is another b-movies actor, Luca Sportelli (no sex):

and also Edmund Purdom (no sex, folks!) and Kjeran Canter

who, as in the other 4 (maybe 5) hard movies I saw featuring him, is not able to perform.
The male cast also includes JP Armand and Guy Bonnafoux. The female has Dominique Saint-Clair, Ajita Wilson, Helene Shirley, Laura Levi, Sabrina Mastrolorenzi and, in the scene with Baldassare, Marcella Petri. That the scene with Baldassarre was hard is confirmed by a correspondent of us who saw the movie in the theatre. We can't establish, as said, if it was made with inserts or not.
