Throughout the series, there are a number of pre-sex or post-sex scenes, wherein couples can be seen lying in bed under the sheets. Some scenes contain sensuality (passionate kissing, caressing), though actual sexual intercourse is never shown. At least one of such scenes features partial female nudity (from the back).
In one scene, an obscene poem is being recited (partially).
In certain episodes some discussions revolve around spousal infidelity and extramarital affairs (though without too explicit details).
