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 form when skin is stretched faster than its dermal connective tissue can adapt: collagen and elastin fibres are disrupted, and the result is a set of 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 sets out how the preference is framed clinically, where it sits in the lineage of partialisms, and how it intersects with body-acceptance culture. As a self-reported taste it is real; as a named category it rests on community description rather than dedicated study.

Definition & scope

The interest is an attraction to a skin texture, not to a body region, which puts it at the fine-grained end of partialism: the sexological term for erotic focus on a specific non-genital body part or feature. Three distinctions matter.

• It is not an interest in injury or damage. Striae are a benign, physiological remodelling of skin, not a wound, and StatPearls classifies them as a common dermatological finding rather than a pathology.
• It is not the same as pregnancy fetishism, though the two often overlap, because striae are only one of pregnancy's many visible changes.
• It is not necessarily a weight- or size-focused interest, though it sits adjacent to preferences such as feederism where a changing body is central.

Most people who describe the preference describe something milder than a fetish in the strict clinical sense: a particular fondness rather than a requirement for arousal.

Examples

The interest becomes much easier to place once it is separated from the several things that sit next to it.

What the term covers. An appreciation of the striations themselves, whether the reddish striae rubrae of a recent mark or the pale, silvered striae albae of an old one, wherever they fall: abdomen, hips, thighs, breasts, buttocks, or upper arms. It covers a purely visual preference, a preference expressed as unhurried attention to the marked areas with a consenting partner, and the very common framing in which someone simply finds a partner's unretouched skin more attractive than the retouched version of it.

What the term does not cover. It is not an interest in injury. Striae are a benign remodelling of skin rather than scarring, which sets the preference apart from stigmatophilia, the attraction to deliberately marked or modified bodies. It is not pregnancy fetishism, which responds to gestation as a whole rather than to one of its traces, and it is not feederism or an interest in weight gain, where a changing body is the point rather than a by-product. It is also narrower than a skin fetish, which takes the whole integument as its object: texture, warmth, scent, sheen, rather than one particular marking on it.

How the word is used. Descriptive vernacular, and recent vernacular at that. There is no clinical coinage and no Greek compound; striae is the dermatological word for the feature, not a name for anyone's interest in it. Neither DSM-5-TR nor ICD-11 lists it, and it reaches clinical attention only through the general route that applies to every partialism: an erotic focus becomes a disorder when, and only when, it causes the person distress or impairment.

History & origins

A feature without its own clinical name

There is no documented coinage, author, or date for an erotic focus on striae. It has never been given a Greek- or Latin-rooted clinical label, 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 bodily features, the intellectual ancestor of every later "-philia."
• 1897–1928: 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: the focuses were consolidated under partialism and absorbed by the DSM and ICD lineages into the general fetishistic/partialism family. A stretch mark fetish reads as a fine-grained instance of that family.
• 2013 → 2022: DSM-5 and the DSM-5-TR settled the modern rule that such an interest is a disorder only where it produces clinically significant distress or impairment, which is why nothing about this preference is inherently clinical.

Why striae became a recognisable focus

Striae are among the most common skin features in the population, which gives the preference an unusually broad pool of subjects. StatPearls reports prevalence of roughly 43–88% in pregnancy, 6–86% across puberty, and around 43% in obesity. Because the marks 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 and broader skin-focused interest. Its emergence as a named preference belongs to the internet era, when image-sharing communities let very specific tastes acquire a label and an audience.

In practice

Expression is mild and largely 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

What causes it?

No dedicated research exists, so any account is borrowed from the general literature on partialism, where a feature becomes erotically salient through individual taste and associative learning rather than through one identifiable mechanism. Clinical commentary on partialism treats such focuses as normal-range variation, pathological only when they cause distress or impairment. Striae carry dense associations: pregnancy, a softer or more mature body, the body's lived history. Any of these could anchor the appeal, and the honest position is that nobody has tested which one does.

Is it normal?

Yes, on the evidence available. It is a normal-range variation, not a paraphilic disorder, and it involves a feature the majority of adults carry.

Prevalence & culture

How common is it?

As a named focus it is rare and essentially unstudied. It does not appear as a discrete category in the standard relative-frequency work: Scorolli et al. (2007) surveyed 381 online fetish discussion groups and found that body parts or features accounted for about 33% of fetish interest, with feet dominating, but it did not resolve interest at the level of a skin texture. Nor does it surface in general-population surveys of paraphilic interest such as Joyal & Carpentier (2017). The figures in this entry are therefore inferred from the entry's place among minor body-feature partialisms and carry low confidence.

Culturally, the visibility of the feature has risen sharply. Body-positivity movements reframe striae as ordinary rather than defective, and cosmetic marketing that once sold their removal now competes with campaigns that show them unretouched. That backdrop 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. StatPearls notes that striae, though benign, can cause considerable psychological distress, and many people feel self-conscious about theirs. Admiration should be offered kindly and never imposed, and a partner's discomfort with attention to the area is the limit that matters. This is not a paraphilic disorder.
