When and why is pain pleasurable?

Many people think of pain and sex as deeply incompatible. After all, sex is all about pleasure, and pain has nothing to do with that, right? Well, for some individuals, pain and pleasure can sometimes overlap in a sexual context, but how come? Continue reading this Spotlight feature to find out.

The relationship between pain and sexual pleasure has lit up the imaginations of many writers and artists, with its undertones of forbidden, mischievous enjoyment.

In 1954, the erotic novel Story of O by Anne Desclos (pen name Pauline Réage) caused a stir in France with its explicit references to bondage and discipline, dominance and submission, sadism and masochism — an array of sexual practices referred to as BDSM, for short.

Recently, the series Fifty Shades of Grey by E. L. James has sold millions of copies worldwide, fuelling the erotic fantasies of its readers.

Still, practices that involve an overlap of pain and pleasure are often shrouded in mystery and mythologized, and people who admit to engaging in rough play in the bedroom often face stigma and unwanted attention.

So what happens when an individual finds pleasure in pain during foreplay or sexual intercourse? Why is pain pleasurable for them, and are there any risks when it comes to engaging in rough play?

In this Spotlight feature, we explain why physical pain can sometimes be a source of pleasure, looking at both physiological and psychological explanations.

Also, we look at possible side effects of rough play and how to cope with them and investigate when the overlap of pain and pleasure is not healthful.

Physical pain as a source of pleasure

First of all, a word of warning: Unless a person is specifically interested in experiencing painful sensations as part of their sexual gratification, sex should not be painful for the people engaging in it.

People may experience pain during intercourse for various health-related reasons, including conditions such as vaginismus, injuries or infections of the vulva or vagina, and injuries or infections of the penis or testicles.

If you experience unwanted pain or any other discomfort in your genitals during sex, it is best to speak to a healthcare professional about it.

Healthy, mutually consenting adults sometimes seek to experience painful sensations as an "enhancer" of sexual pleasure and arousal. This can be as part of BDSM practices or simply an occasional kink to spice up one's sex life.

But how can pain ever be pleasurable? According to evolutionary theory, for humans and other mammals, pain functions largely as a warning system, denoting the danger of a physical threat. For instance, getting burned or scalded hurts, and this discourages us from stepping into a fire and getting burned to a crisp or drinking boiling water and damaging our bodies irreversibly.

Yet, physiologically speaking, pain and pleasure have more in common than one might think. Research has shown that sensations of pain and pleasure activate the same neural mechanismsin the brain.

Pleasure and pain are both tied to the interacting dopamine and opioid systems in the brain, which regulate neurotransmitters that are involved in reward- or motivation-driven behaviors, which include eating, drinking, and sex.

In terms of brain regions, both pleasure and pain seem to activate the nucleus accumbens, the pallidum, and the amygdala, which are involved in the brain's reward system, regulating motivation-driven behaviors.

Thus, the "high" experienced by people who find painful sensations sexually arousing is similar to that experienced by athletes as they push their bodies to the limit.
