Damn these people are clowns. Prudes are inherently evil. And also extremely stupid.
First 50 I can think of off the top of my head were the actual sex scene or scenes are essential and I believe the movie is at least passably good:
A History of Violence
Boogie Nights
The Shape of Water
Mullholland Drive
Gone Girl
Blue Velvet
Oldboy
The Piano Teacher
Lost Highway
Portrait of a Lady on Fire
The Dreamers
True Lies
Basic Instinct
Species
It Follows
Eyes Wide Shut
Splice
American Beauty
Your Friends and Neighbors
The Terminator
Geraldโs Game
Bound
In the Realm of the Senses
Lust, Caution
Y tu mama tambiรฉn
Poor Things
The Handmaiden
Zac and Miri Make a Porno
The Room
Crash
Laurel Canyon
9 1/2 Weeks
Revenge
The English Patient
Antichrist
The Town
Red Sparrow
Blue is the Warmest Color
Blood Simple
Carol
Closer
Unfaithful
Singles
Party Girl
Luckiest Girl Alive
The Accused
Thank You For Smoking
The Departed
Atonement
The Wolf of Wall Street
Not that it matters; life has sex and so should movies even if not essential to the plot. Pretending otherwise is daft and childish.
