horror movie

i saw a cheesy horror movie,prob 80's cant remember the name,its about a couple,the man works,his wife stays home ..he dosent want her to work,but she writes these erotic stories for a mag to make a few dollars and he reads them one by one and thinks his wife is cheeting on him(as he reads them the background goes red) ha! anyway he starts killing off the ppl one by one,(one story is about the mailman so he killes the mail man) then he finds out they are stories ..its a cheesy movie,but i loved it and i need to see it again!
