There is a lot of suggestive marital and open discussion about sex.
The movie opens with a man at a bachelor party and there is a stripper. She is only where a bra with balloons on it and a thong. She dances suggestively and even gets on her head and wraps her legs around the groom to be and then pulls herself up in order to have her crotch in his face. A old man see her and is so aroused that he is put in the hospital where we learn that he was "never attracted to his wife" and would often imagine himself with younger women.
Passionate kissing and licking of the chin and face.
An older couple admit they are having and affair and she says that she thought sex was just a burden until she met this man and now knows what a true orgasm is.
A woman takes a bath and we see her naked from the behind, waist up. We can see her silhouette undressing through a blue glass wall.
The best man encourages the groom to sleep with as many women as he can before he gets married.
A woman undresses and she and a man fight while she is in her underwear, bra and panties. This scene lasts for a few minutes.
We see a clothed couple kissing and cuddling in bed and a clothed man lying on top of a clothed woman, kissing her, she stops him.
For a strip-tease act, a woman undresses a man down to his boxers in front of many other men (we see a bit of his bare chest as he opens and closes his unbuttoned shirt).
