Shortbus

Set in New York City, the movie follows two occasionally intersecting narratives. The first revolves around Sofia, a sex therapist who has never achieved orgasm in her life, and the strain it puts on her relationship. After attending the Studio 54-esque club Shortbus, Sofia befriends professional dominatrix Severin, who tries to help her finally find orgasm.

The second revolves around James, an amateur filmmaker and former hustler who is morose and introverted. He and his boyfriend, Jamie, begin an open relationship with a third man, while a fourth, named Caleb, stalks James from his apartment one block over. The film James has been working on turns out to have an unpleasant surprise...

While Shortbus has largely been overshadowed by Hedwig and The Angry Inch, it remains a quirky and off-beat flick with its own merits. If nothing else, it has lots and lots of sex in it.

Tropes used in Shortbus include:

Big Blackout
Bigger Is Better in Bed: Not actually discussed, but there can't be a single penis seen in the film less than seven inches long (6 1/2 minimum).
Brains and Bondage: Severin.
Cameo: Many, mostly of New York artists, musicians, and writers, and John Cameron Mitchell himself.
A Date with Rosie Palms
Embarrassing First Name: Severin's real name is Jennifer Aniston.
Epiphany Therapy
Everyone Is Bi: Except for the characters who are gay.
Interrupted Suicide
Love Dodecahedron
Meaningful Name: Severin, taken from the protagonist of Venus in Furs. Also a subversion, as Severin is the submissive part in Venus in Furs.
My Girl Is a Slut
Naked on Arrival: The opening scene are different sex scenes inter-cut with each other, including James attempting autofellatio.
Nobody Over 50 Is Gay: Averted with Tobias, who most certainly does not resemble Ed Koch.
Rescue Romance
Shout-Out: A vibrating egg has the phrase In the Realm of the Senses written on it. And yes, it is inserted into one of the main characters' vagina.
Stalking Is Love
Transvestite: Justin Bond.
Turn of the Millennium: Referencing many current events and trends of the early 00s, including The War on Terror, 9/11, and the New York City blackout.
The Twink: Ceth, to some extent.
