You might want to check out the follow up PORNO HOLOCAUST which features a zombie with a huge penis shagging women to death and smashing men's heads in rocks.
I've actually got Porno Holocaust on an actual proper DVD. Bought it out of curiosity. Released on a German label X Rated Kult DVD. Comes in a rather cool replica of the old rental VHS cases. Mind boggling stuff.
