Sexual dialogue occurs throughout the series. The purpose of this dialogue is to show that men in the sixties were sexist and objectified women. Furthermore, most of the main characters are married men who are openly carousing with other women. Women are encouraged to objectify themselves by wearing more showy clothing in order to please their bosses. A frequent theme of the show is that women are treated like tramps if they act the same way that men do.
The main characters are often seen making out with their partners. In some instances, they tease the other by placing their hands at the other person's crotch or kissing the chest.
