There is no blood but he reacts with obvious pain and you can see red welts begin to develop where she hits him. She proceeds to viciously whip him with a belt while yelling at him. Its played for laughs (he says things like 'lets get to know each other first? and tried to get her to wear a fake beard) but the scene is very real.
In the dominatrix scene, a fully exposed woman wearing dominatrix gear rips the clothes off a man a tries to force him to have sex with her. There is also a penis which appears, and dances around for an extended period of time, then the camera zooms in on the urethra, which opens like a mouth and screams 'Bruno!'. There is full frontals of both woman and men, an explicit swingers party, explicit gay sex acts, and a violent dominatrix scene. There is adult language and some minor violence, but the major concern is all the nudity and sex acts. Its funny, but in a sarcastic and possibly offensive way.
Anyone who would let their children be exposed to this shouldn't even be on this site.
