Little actual nudity, but several sex scenes, mostly implied or discreetly photographed by showing only bedsheets moving. There are two orgasm scenes. There are also a few scenes where sex is discussed.
In one scene the characters passionately kiss and undress. They are naked during the sex scene, but little is shown - basically side views of the couple.
In another scene the two people are completely under the sheets the entire time they are having sex - even their heads. After finishing the female character gets out from under the sheets and lies there on her back - her breasts are visible. In the next scene she walks into a bathroom naked and stands in front of a mirror - she is shown naked from the waist up throughout this scene. Male nudity is limited to bare chest.
