Costello wants Colin to take care of police problems and thus suggests something might happen to Madolyn if he doesn't.

A woman shows some cleavage.
A man sits in an adult theater watching a pornographic movie he then stands up and reveals a dildo from under his coat. Colin then hears male sexual sounds coming from a few rows in front of him as a man then stands up and holds a large dildo in front of his pants. It's Costello, just joking around with Colin, telling him he owns the place, but that since it's always easy for him to get "cunt," he never understands people "jacking off" in the theater. Needing a place to meet Costello, Colin goes into a porn theater where we see clips of a porn film playing on the screen (and otherwise hear its audio with some sexually related sounds), but don't see anything explicit.
A man and a woman passionately kiss and we see the beginnings of them starting to have sex, they lay down on a bed and continue to kiss. The man is seen shirtless while the woman is stripped to her undergarments. The camera lingers on for a long time, with closeups of both of them almost nude.
Costello says that he doesn't need "pussy" anymore, but that he likes it.

A painting in the background of a shot shows a bare-breasted woman holding some small material over her crotch.
After Costello makes an angry call (including talk of someone crawling up another's "ass"), he tells his woman, "You're giving me a hard on." She then playfully asks if he's sure that's not from all of the crawling up the "ass" talk. He tells her to watch her mouth, and she replies, "No, you watch it. Let me straighten you out" as she suggestively goes over to him (presumably to perform oral sex, but we don't see that occur).
Costello is mad about where a subordinate dumped a body, telling him you don't do that "where a guy goes to get a blowjob."
Madolyn shows Colin her ultrasound, showing that she's pregnant and points out a little speck that she says is the baby's penis. The two then roll around on the bed (clothed), with him ending up between her legs.
Costello tells a hooker to bend over and says "don't move till you're numb" implying that they're going to perform anal sex; the scene is not shown.
