Wisconsin Statutes Crimes (Ch. 938 to 951) § 944.01. Intent

The state recognizes that it has a duty to encourage high moral standards. Although the state does not regulate the private sexual activity of consenting adults, the state does not condone or encourage any form of sexual conduct outside the institution of marriage. Marriage is the foundation of family and society. Its stability is basic to morality and civilization, and of vital interest to society and this state.
