Man in shower rooms shirtless. Man sits naked in bathtub; nothing explicit is seen.
A man and a woman kiss a couple of times. One time, it leads to sex, off camera. They are shown next morning, under the sheets and have sex again. This time the woman's breast is visible for a couple of seconds.
Same man and woman later have sex under sheets. It is relatively brief, there is some moaning and movement. At the end she comes out from under the sheets but she is wearing a bra, him a t-shirt. The sheet continues to cover them from the waist down.
The leads start kissing, then passionately. No sex or nudity in this scene.
Max is describing Florida, and speaks of grapefruits the size of your head (meaning breasts).
Henry and Debbie speak of screwing a few times.
The grapefruit discussion comes up again.
