I saw the trailer and there's some heterosexual face eating :>
Around 27 minutes you see a woman (possibly a prostitute) lying in bed and you see her cleavage and quite a few more times in the next minute+ and then she shakes her covered breasts at the men when they leave
A prostitute is shown in a room with two men (one of whom is asleep in a chair) and the other is sitting in the edge of the bed where the prostitute is lying (fully clothed). He stands up in his long johns and they leave (presumably after sex).
A man and a woman kiss passionately. The woman stands up and leads the man inside. The man closes the door, implying sex
A man and a woman can be heard in a bed. The woman then turns on a lamp and is lying on top of the man. Both are under the blanket (presumably after sex).
A woman and her husband are in bed together at night and she asks him for a back rub. He rubs her back and the woman groans (delighted from the back rub). The man's brother is in another room and hearing the moaning, thinks that the couple is having sex.
A man and his deceased brother's wife are romantically inclined after the brother is killed.
