Anya and Michael have sex, she wears a bra, he's shirtless, seen from mid-chest up. Maya and Jack meet for sex, some sexual dialog. Several women frequently seem in underwear or swimwear.
Maya seen showering twice, no nudity seen. Maya tries to seduce Leo, drops her towel, bare rear seen (but probably a body double since hair is a different shade and wavier). Both are seen the next morning in underwear, implying they had sex. Later Maya and Leo seen having sex, show from the shoulders up, no nudity.
