Harley Quinn is seen in very revealing clothes throughout. The Joker's paints contain an amateur drawing of a penis. However, it is not seen often
Joker makes many sexual references
Bruce Wayne and Selena Kyle are seen having sex. They make out on a bed and Bruce is seen grabbing her butt. She then takes off her top and pulls her panties off; her naked body is clearly seen. The scene ends with Bruce and Selena lying side by side on the bed, with Selena's breasts seen
Harley Quinn starts to annoy Joker and in one scene he savagely beats her up. He then forces her on a wall and pulls her panties down. He thrusts into her and we see her butt. Not much nudity, but graphic nonetheless
Wonder Woman's outfit shows cleavage. In one scene, a child is seen staring at her chest area (played for dark humor)
Alfred walks in on Bruce Wayne having sex with his mistress. They are covered in a blanket, so no nudity seen. However when she gets up, her breasts are seen briefly
Barbara Gordon undresses in front of her father. The father doesn't look, but we see her jiggle her breasts and slightly tease her pubic area. Not much nudity seen
In a flashback, Bruce and his parents are seen walking through the streets. Bruce notices two silhouettes thrusting into each other in an alley before his mother quickly turns him away. No nudity seen, but nudity is implied
DELETED SCENE: The Joker forces Harley Quinn to seduce Batman so that he can steal a bag of diamonds from him. Harley talks to Bruce in his bedroom while slowly undressing herself, eventually revealing full frontal nudity. The movie cuts to Bruce's naked torso thrusting into Harley's buttocks, and his penis is clearly seen going in and out. Moaning is very loud and nudity is clear. Scene lasts for about 15 seconds and is the most graphic sex in the film
The Joker forces a little boy to perform fellatio on him. It almost happens, but Batman pushes him aside in time
