There are a handful of scenes where women and men are nude, mostly in scenes leading up to or following after sex, but sexual activity itself isn't shown except for the opening scene of the first episode of season 2. These scenes are usually short; breasts, butts are visible. Almost no nudity in the whole 3 seasons. Some extra-marital activity occurs and affects plot lines.
