A young man and a young woman kiss very briefly. She leaves the room and tells him that she uses contraceptive gel because she can't use the pill. The man leaves the room and she removes her top and gets under the covers (her breasts are seen). Later in the same scene, the young man says he couldn't have sex with her because of her birds watching them and that 'sick' gel. In another scene, he tells the girl her birds made him uncomfortable.

A woman takes off her robe (rear nudity) and gets into bed with a young man. She asks him if he wants to sleep with her and it is implied they have sex. They talk about it as a one-time thing in a later scene, without using any graphic terms.
