We see the side of a woman's breast before she puts on a shirt, then we see her breasts and midriff through her slightly transparent top; we also see a woman wearing a bra in two different scenes, many women in bathing suits and cleavage and/or midriff-revealing tops, a few men in bathing suits, and a woman wearing a towel.
A man and woman kiss passionately and move to a couch; then he begins putting his hand under her dress and becomes forceful (please see Violence/Gore for more details).
A woman unzips her dress and lets it fall off, then starts kissing a man. No nudity is visible in the PG-13 theatrical version. However, in the extended version (which is available in the UK, with a 12 rating), the woman's breasts are visible and the man starts kissing her naval area
It's implied that a woman has to have intercourse with a man because her boyfriend lost a pool game (we only see the clothed man lying on the pool table and the woman closing the doors to the room).
Two women kiss, and one pulls the other's shirt up a little (no nudity is visible, and there's no further sexual contact). We briefly see a shirtless man and a woman wearing a bikini kissing.
A woman tells another that she had sexual fantasies about her psychiatrist; also, there's mention of semen found on a woman's dress.
A man somewhat suggestively tells a woman to widen her golf stance, then (in a close-up shot) puts his hands on her inner thighs and pushes them further apart.
Two women dance suggestively with each other and with a man; he runs his hands up one woman's clothed torso, and she pulls up his shirt and touches his torso.
At a party, a woman's bikini top is untied (she holds her arms over her breasts, so no nudity is visible).
