Issues concerning women's bodily integrity and autonomy, such as abortion, rape, and sterilization, are subject to strong opinions that give rise to equally charged political policies. As with other issues pertaining to women's bodies, prostitution discourse is largely concerned with determining whether this social practice is exploitative, empowering, or a consequence of immorality. Prostitution is here defined as a social practice by which men gain sexual access to the bodies of predominantly women, children, and sometimes other men, through the exchange of money, goods, or housing. Prostitution, as a social construct, arises from "men's dominance and women's subordination." Most people take one of three salient positions on prostitution. The first position argues that prostitution is a consequence of deficient moral character. This position draws heavily from patriarchal and religious traditions that equate female sexuality with temptation and male sexuality with dominance and sanctioned insatiability. The second position, the "sex work" position, asserts that prostitution is a valid form of labor and argues that prostitution is not inherently harmful to women. This position further contends that women have a right to decide what they will do with their bodies and that sex work, though oppressive for some, is potentially both lucrative and empowering for other women. The third position asserts that prostitution is a consequence of social, political, and economic inequality and argues that women are predominantly conscripted into prostitution because of their social vulnerability. Political regulation of prostitution activity varies according to each nation's underlying economic and social justice commitments.
