Sexual references throughout, ranging from double entendres to jokes to conversations. Some are mild, others more explicit.
One scene with a couple in bed, but no nudity.
Brief shot of a man inspecting two men wearing Speedos (they're shown from the waist down); he then makes a crude comment about them.
In the opening credits, a man is shown thrusting an unseen woman who's legs are open in the air. He's on the phone and exclaims "I'm coming!" (this is most likely a reference to the theme of the credits). No nudity other than his bare chest but easily the most graphic scene in the film.
Man tell his girlfriend he can come upstairs and wake her up with his penis.
One scene shows multiple females in bikinis.
Multiple couples are shown kissing/making out.
