How Does Our Brain Generate Sexual Pleasure?

An Evolutionary Psychological Approach Toward BDSM Interest and Behavior

Bondage/discipline, Dominance/submission, and Sadism/Masochism (BDSM) have gained increased attention and discussion in recent years. This prevalence is accompanied by a shift in perceptions of BDSM, including the declassification of sadomasochism as a paraphilic disorder. Evolutionary psychology offers a unique perspective of why some individuals are interested in BDSM and why some prefer certain elements of BDSM over others (e.g., dominance versus submission). In this paper, we examine BDSM from an evolutionary standpoint, examining biopsychosocial factors that underlie the BDSM interests and practice. We articulate this perspective via an exploration of: proximate processes, such as the role of childhood experiences, sexual conditioning, and physiological factors; as well as ultimate explanations for power play and pain play dimensions of BDSM, highlighting the potential adaptive advantages of each. While BDSM may not be adaptive in itself, we examine the literature of sex differences in BDSM role preferences and argue that these preferences may stem from the extreme forms of behaviors which enhance reproductive success. In the realm of pain play, we explore the intersection of pain and pleasure from both physiological and psychological perspectives, highlighting the crucial role of psychological and play partner factors in modulating the experience of pain. Finally, we encourage future research in social sciences to utilize evolutionary frameworks to further explore the subject and help alleviate the mystification surrounding BDSM. This multifaceted exploration of BDSM provides valuable insights for clinicians, kink-identified individuals, and scholars seeking to understand the evolutionary perspectives of human sexual behavior and preferences.

Sexual Pleasure Matters - and How to Define and Assess It Too. A Conceptual Framework of Sexual Pleasure and the Sexual Response

Objective

Sexual pleasure is central to current understandings of sexual function, health, and wellbeing. In this article, we suggest that we lack a sufficiently specific, yet encompassing, definition of sexual pleasure and that we therefore lack comprehensive assessments of sexual pleasure. We introduce a definition of sexual pleasure and position it centrally in an adapted framework of the sexual response. In the framework, we include a taxonomy of rewards which can be retrieved from sex and thereby aim to capture the multifaceted nature of sexual pleasure.

Methods/Results

Through narrative review, we arrive at the definition, framework, and taxonomy by integrating theories of sexual motivation and response with the literature on sexual pleasure and basic rewards. We position this literature within theories of affect and personality which allows us to differentiate between the experience of and the tendency to experience sexual pleasure (i.e., state versus trait sexual pleasure). We discuss how this conceptualization of sexual pleasure could be reflected in self-report assessments to quantitatively assess sexual pleasure.

Conclusions

The framework may aid to understand the role of the diverse facets of sexual pleasure in sexual function, health, and wellbeing and contribute to giving sexual pleasure the center position it deserves in sex research and therapy.

Advancing Sexual Pleasure as a Fundamental Human Right and Essential for Sexual Health, Overall Health and Well-Being: An Introduction to the Special Issue on Sexual Pleasure

On September 11, 2021, the World Association for Sexual Health ratified a Declaration on Sexual Pleasure in its General Assembly. This declaration was a bold attempt by WAS to urge all spheres of influence in society to recognize the critical importance of sexual pleasure as a key component of sexual health and sexual rights. This special issue of the International Journal of Sexual Health (the official journal of the WAS) contains a technical document which supports the Declaration. In addition, it contains background papers that were commissioned to inform the evidence supporting the technical document and to outline the strategies for implementing the WAS Declaration on Sexual Pleasure in promoting sexual health and rights.
