Stretch Mark Fetish

Stretch mark fetish is a body-feature partialism in which stretch marks, the linear skin striations known clinically as striae (or striae distensae), are a focus of erotic interest. Striae are a common, benign feature: they form when skin stretches faster than its dermal connective tissue can adapt, and the resulting disruption of collagen and elastin leaves fine streaks across the abdomen, hips, thighs, breasts, buttocks, or upper arms. For someone with this interest, that texture reads as attractive rather than as a flaw. This article covers how the interest is framed clinically, where it sits in the lineage of partialisms, and how it intersects with body-acceptance culture. As a self-reported preference it is real; as a named category it rests on community description rather than dedicated study.

History & origins

A feature without its own clinical name

There is no documented coinage, author, or date for an erotic focus on striae specifically: it has never been given a Greek- or Latin-rooted clinical label of its own, and it does not appear in the standard catalogues of named paraphilias. What is documented is the broader frame it belongs to.

• 1886: Richard von Krafft-Ebing's Psychopathia Sexualis established the case-study tradition of cataloguing erotic focuses on particular features, the intellectual ancestor of every later "-philia."
• 1890s–1920s: Havelock Ellis's Studies in the Psychology of Sex treated such preferences as variations along a continuum rather than discrete diseases, softening the pathologising tone.
• 20th century onward: these focuses were formalised under the sexological concept of partialism, an erotic emphasis on a specific non-genital body part or feature, which the DSM and ICD lineages eventually absorbed into the general category of fetishistic/partialism phenomena. A stretch mark fetish is best read as a fine-grained instance of this category, a focus on a skin texture rather than a whole region.

Why striae became a recognisable focus

Striae are among the most common skin features in the population. StatPearls reports prevalence ranging roughly 43–88% in pregnancy, 6–86% across puberty, and around 43% in obesity, and Wikipedia cites figures of about 90% for pregnancy. Because striae are so strongly associated with pregnancy, with a fuller or changing body, and with the visible record of growth, the erotic interest tends to be discussed alongside pregnancy fetishism, broader skin-focused interest, and weight- or feeding-oriented preferences such as feederism. Its emergence as a named preference is a product of the internet era, when image-sharing communities let very specific tastes find a label and an audience.

In practice

The interest is typically expressed through visual appreciation of striated skin and, with a consenting partner, gentle attention to the marked areas. Because stretch marks are so widely shared, the preference often surfaces simply as finding a partner's natural skin attractive: a framing many describe in explicitly body-positive terms, as the inverse of the cultural pressure to erase striae. Online it appears in niche forum threads and image-sharing spaces adjacent to pregnancy and body-acceptance communities rather than as a large standalone scene.

Psychology

The interest fits the general pattern of partialisms, in which a feature becomes erotically salient through individual taste and associative learning rather than through any single mechanism. As clinical commentary on partialism notes, such focuses are a normal-range variation and are considered a disorder only when they cause distress or impairment. Stretch marks carry rich associations (pregnancy, a softer or more mature body, the body's lived history) and any of these may anchor the appeal; the evidence base for which of them does is essentially nonexistent, since the focus has not been studied directly. It is a normal-range variation, not a paraphilic disorder.

Prevalence & culture

As a named focus this is rare and essentially unstudied: it does not appear as a discrete category in the standard relative-frequency surveys of fetishes (for example Scorolli et al. (2007) on the relative prevalence of online fetish interest, or Joyal & Carpentier (2017) on paraphilic interests in the general population), and it has no clinical literature of its own. The figures in this entry are therefore inferred from its place among minor body-feature partialisms and carry low confidence. Culturally, the visibility of stretch marks themselves has risen sharply through body-positivity movements that reframe striae as normal rather than a defect: a sympathetic backdrop that normalises the underlying feature, even as the explicit erotic preference stays niche.

Safety, consent & law

This is a benign interest with no inherent safety or legal concerns beyond ordinary consent; it involves a naturally occurring, harmless skin feature and no risky activity. The one meaningful caution is social: many people feel self-conscious about their stretch marks, and StatPearls notes that striae, though benign, can cause significant psychological distress. Admiration should therefore be communicated kindly and never imposed. This is not a paraphilic disorder.
