Erotic lactation
sexual arousal by breastfeeding on a woman's breast
Erotic lactation (clinically known as milk fetishism or lactophilia) is sexual arousal from breastfeeding or sucking on a female breast. It may occur in the context of an adult nursing relationship (ANR). The clinical terms are classified as paraphilias in systems such as the ICD-10 and DSM-IV, but when practiced consensually between adults, erotic lactation can serve erotic, emotional, or nurturing purposes without being considered a disorder.
Physiology
Breasts, and especially nipples, are highly erogenous zones, for both men and women. Nipple and breast stimulation of women are a near-universal aspect of human sexuality, though men's nipples are not as sexualized. Humans are the only primates whose female members have permanently enlarged breasts after the onset of puberty; the breasts of other primate species are enlarged only during pregnancy and nursing. One hypothesis postulates that the breasts grew as a frontal counterpart to the buttocks as primates became upright in order to attract mates, a model first developed in 1967. Other hypotheses include that by chance breasts act as a cushion for infant heads, are a signal of fertility, or elevate the infant's head in breastfeeding to prevent suffocation. Paradoxically, there is even a school that believes that they are an evolutionary flaw, and can actually suffocate a nursing infant.
The association of pleasure and nutrition holds true as well for the lips, also erogenous zones, where pleasure may have led to "kiss feeding", in which mothers chew food before passing it on to the child.

Why this record matters
The phrase “sexual arousal by breastfeeding on a woman's breast” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 14, 2026. The linked authority identifier is Q1269174. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1967.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
