The Elven Bride(1995)

Follow along now: we've got a human (male, of course) and an elf (female, of course) and they want to get married. Naturally, this isn't going to go as planned... and it seems that we're in for some lessons on biology before we're done with this one. So, they may have lots of love between them, but elf-wife Milfa and her human-hubby Kenji are still having considerable... um... trouble in the bedroom. So, after her husband trots off on his daily journey, Milfa sets off on a quest of her own!
