According to the book Body parts: critical explorations in corporeality, adult nursing may occur when an "individual, usually a mother, may choose to continue lactating after weaning a child, so that she avoids the significant physical challenge that inducing lactation can entail." However, milk production can be "artificially" and intentionally induced in the absence of any pregnancy in the woman.Breastfeeding mothers have faced legal ramifications for nursing their children into toddlerhood or in public, or for photographing themselves while nursing.Researcher Nikki Sullivan, in her book A Critical Introduction to Queer Theory, calls erotic lactation a manifestation of "Queer." She defines Queer as an ideology; that is, as a "sort of vague and indefinable set of practices and (political) positions that has the potential to challenge normative knowledges and identities." Drawing on a statement of David Halperin, she continues "since queer is a positionality rather than an identity in the humanist sense, it is not restricted to gays and lesbians but can be taken up by anyone who feels marginalised as a result of their sexual practices." The heteronormative profile of breastfeeding assumes certain norms: Any kind of sexual activity which includes the woman's milk.Nipple and breast stimulation of women are a near-universal aspect of human sexuality, though nipples in males are not as sexualized.
