'Necromania': A Tale of Weird Love! (1971)

Necromania (sometimes subtitled A Tale of Weird Love) is a pornographic film by Edward D. Wood, Jr., released in 1971.
Thought lost for years, it resurfaced in edited form on Mike Vraney's Something Weird imprint in the late 1980s, then was re-released on DVD by Fleshbot Films in 2005. Opening titles indicate "Produced & directed by Don Miller. Our cast wish to remain anonymous."
The plot (based on Wood's novel The Only House) involves a couple, Danny and Shirley, who visit necromancer Madame Heles for a witchcraft solution to Danny's erectile dysfunction.
