Sexual capital or erotic capital is the social value an individual or group accrues as a result of their sexual attractiveness. As with other forms of capital, sexual capital is convertible, and may be useful in acquiring other forms of capital, including social capital and economic capital. Sexual capital or erotic capital is the social value an individual or group accrues as a result of their sexual attractiveness. As with other forms of capital, sexual capital is convertible, and may be useful in acquiring other forms of capital, including social capital and economic capital. The term erotic capital was first used by British sociologist Catherine Hakim in the early 2000s. Hakim defined it as separate from and building upon French sociologist Pierre Bourdieu's concepts of economic, cultural and social capital. She says erotic capital is independent of class origin and therefore enables social mobility, and argues that this makes erotic capital socially subversive, which results in the prevailing power structures devaluing and trying to suppress it. In the manosphere, the parallel term sexual market value or its abbreviation SMV is often used. One economic-related definition is based on the human truth capital theory of Gary Becker, and predicts that people invest rationally in exhibiting their sex appeal when they can expect a return on their investments. This he defines as a form of health capital which is itself a form of individual capital. The sociological definition is based on Bourdieu's idea of fields.This definition builds on Bourdieu's concept of capital. Green defines sexual capital as accruing to an individual or group due to the quality and quantity of attributes that he or she possesses which elicit an erotic response in another, including physical appearance, affect and sociocultural styles. Some of these attributes may be immutable, such as an individual's race or height, while others may be acquired through fitness training, or artificially, through plastic surgery or a makeover, etc. There is no single hegemonic form of erotic (sexual) capital. On the contrary, currencies of capital are quite variable, acquiring a hegemonic status in relation to the erotic preferences of highly specialized social groups that distinguish one sexual field from another. Importantly, this means that erotic capital is best conceived as a property of the field, and not an individual form of capital. A second definition is developed by Hakim, treating erotic capital as the fourth personal asset. This definition is a multifaceted combination of physical and social attractiveness that goes well beyond sexual attractiveness that is the focus of the 'fields' perspective. Unlike Green's conception of sexual capital, Hakim's erotic capital is an individual capital with no necessary referent to a field. Extensive supporting evidence for the concept of sexual capital, defined as beauty, physical attractiveness, and good looks, is provided in Daniel Hamermesh's latest book, Beauty Pays, where he reviews the research evidence on the economic benefits of being attractive in all contexts, including higher education teaching, politics, sales and marketing, and everyday social interaction. Hamermesh assumes these economic benefits must be due to unfair discrimination, a position he takes from Deborah Rhode's new book, Beauty Bias, a feminist lawyer's critique of the social benefits that accrue to attractive people, and the disadvantages experienced by unattractive people, most particularly the obese. Catherine Hakim argues that erotic capital matters beyond the sexual field, and beyond private relationships. Her research suggests that erotic capital is important in the fields of media, politics, advertising, sports, the arts, and in everyday social interaction, and consists of six elements: Catherine Hakim's theory of erotic capital argues that erotic capital is an important fourth personal asset, alongside economic capital, cultural/human capital and social capital; that erotic capital is increasingly important in affluent modern societies; that women generally have more erotic capital than men, and that erotic capital has social benefits and privileges that benefit the female gender. This definition of erotic capital has been contested by some sociologists who reject the idea that erotic capital / sexual capital is something individuals possess, like a portable portfolio of resources, with no implicit link to the particular sexual field in which such characteristics are deemed desirable. Sexual capital may be related to both sexual and mental health, as when individuals with low sexual capital show diminished ability to talk about or negotiate condom use with a partner possessing greater erotic capital, and develop negative emotional states as a consequence of feeling unattractive.
