The most infamous example of sexual imagery run amok is the result of disturbing artist H.R. Giger and director Riley Scott. The entire Alien franchise is nothing but dicks and butts and vaginas that want to hump you into oblivion. It's not enough that it's sexual imagery; it's sexual imagery that wants to hurt you so bad, you feel like you're watching Prometheus.
We've told you before about how the aliens are just giant penises with even smaller penises in their constantly ejaculating mouths, and how the chambers in the alien pilot vessels are all accessed through giant vaginas, but if you try to actually add up all the imagery in just one Alien movie, you'll be up to your neck in labia and foreskins before the third act. Look at the face hugger. It's an ass with a vagina on the bottom and penis fingers. The vagina is actually at the end of a penis that gets forced down your throat once the penis fingers hug your head and squeeze its butt-body all tight against you. It then proceeds to peen-vag your throat so hard that you end up with a baby penis-headed monster inside you that explodes its own birth canal out of your chest.
So ... was it good for you?
The alien Queen has a giant vag chute that deposits gross eggs everywhere, each one a big, green seed pod with huge labia on top. Whenever someone gets close enough to stimulate them, the labia spread wide open. The Queen's tail is a massive dong that rips Bishop in half through the process of penetrating him -- he gets fucked right in half!
