A woman from Earth crash lands on a planet where she discovers other forms of making love.
Somewhere in the middle of the movie, she finds herself in a city of women with a man inside a giant bubble with liquid. She is offered a hookah-like device to smoke some "essence of man".
At the end of the movie, she has sex the "normal" way which, in the future, involves taking a pill and pressing your hands against your partner. Fully clothed.
Nevermind, I found it!
