A woman injures her vagina/groin on a bicycle. It's mentioned verbally but in a non-sexual context.
A woman stands fully nude in front of a man as a "preview" for the sex they are going to have-- she is not in focus so details are indiscernible. She is shown from behind in a very darkened silhouette. They get into bed to make love and her breast is seen, though the nipple is covered partially by her arm. She mounts him and thrusts several times as they talk and she admires herself in a mirror above the bed-- something that he comments as being "hot". Neither genitals nor female nipples are shown, but the scene isn't brief.
Lots of girls in bikinis, very revealing.
