Third, INVASION OF THE BEE GIRLS (1971)!
What is it about the 1970s that every film to come out of the decade was coated in a thin layer of grease? And IotBG is one of the greasier, featuring no less than four sex scenes in the first twenty minutes and a fairly graphic rape scene in the back nine.
The goofy “women genetically crossed with bees need sex to live” plot would be embarrassing enough on its own, but combined with the cavalier attitude towards sexual violence the plot makes for a pretty gross flick. Definitely needed a shower after this one.
