The Dark Side of the Big “O”


Let’s Talk!

Many books on sexuality promote orgasm as the ultimate goal of sexual encounters. Also, most men view making their woman come as proof that they are good lovers. However, there is dark side to frequent intense orgasms, and it is rarely discussed. This hidden negative effect can put both our emotional health and the harmony of our romantic relationships at risk.

Orgasm happens in the brain, although obvious bodily changes are observed during sexual arousal. The electric impulses of nerve cells found in the limbic system are responsible for the experience of orgasm. The limbic system is the seat of uncontrollable primal drives, impulses and all kinds of desires, which include sexual desire (see picture below). This system is located right beneath the large, rational neo-cortex, and mating behaviours involve both the activation and deactivation of certain of its parts.

Brain Limbic System (left side view)

The centerpiece of the limbic system is the reward circuitry and dopamine is the principal neurochemical that activates this circuitry (see picture below). Dopamine is a catecholamine neurotransmitter that is produced by neurons whenever you engage in activities that support your survival (i.e., sex, eating, achieving goals). The more dopamine neurons release, the more your reward circuit is activated, and the greater your desire for that particular thing.

Brain Reward Circuitry (VTA=Ventral Tegmental Area)

Dopamine is insatiable, and loves newness as well as the unexpected (see molecular structure below). It also controls cravings, but after we have obtained the object of our desire, opioids such as morphine and endorphins enable us to enjoy the experience.

2D Structure of Neurotransmitter Dopamine

Addiction is closely linked to dopamine, and any substance (i.e., cocaine) that stimulates the dopamine production may be addictive. Our natural production of dopamine is at its highest during orgasms, especially following intercourse for both males and females. In fact, brains that are experiencing the big “O” resemble those experiencing a heroin rush.

Nerve cell receptors that are exposed to high doses of dopamine become less sensitive to this neurotransmitter as the brain tries to calm itself down. Over time, there may be fewer of these dopamine receptors and more intense stimuli are needed to produce the same high. Furthermore, the amount of the neurohormone prolactin greatly increases, which creates a sensation of sexual satiation, but also the temporary inability to have another orgasm right away. Prolactin also suppresses dopamine and therefore acts as the “brakes” for orgasm.

Other brain chemical changes occur. Enkephalins (endogenous opioids) increase and inhibit oxytocin (the bonding hormone). Oxytocin may be produced because of the muscle contractions that accompany orgasm. This interaction of brain chemical results in an overall decrease of feelings of satisfaction.

Similarly to other addictive substances, intense orgasms produce an initial powerful pleasurable experience, but is followed by a “hangover” effect. This “hangover” is the result of the sudden drop of dopamine in the brain, and we may become irritable for about two weeks.

Even small changes in neuron sensitivity or production of dopamine can have a profound effect on our perception of the world and our partners. Dopamine helps us bond with our partner, and if this neurotransmitter decreases, we may find our love interest less rewarding and the bond may be strained.

Since few people are aware of the link between dopamine and orgasm, many feel moody after an intense sex session, and do not understand why. Some may try to medicate these blues by eating, drinking alcohol or watching porn in an unconscious attempt to raise their dopamine level. However, these “solutions” only aggravate the problem by again raising dopamine to an abnormally high level.

It is interesting to note that very sexually active individuals tend to be prone to other types of addictions. The dopamine rollercoaster may prompt these individuals to medicate themselves in an attempt to normalize their brain chemistry.

One of the major risks of this dopamine cycle is that this neurotransmitter thrives on novelty. Even after being sexually satiated, many people (especially men) can easily get aroused in the presence of a new sexual partner. This phenomenon is called the “Coolidge Effect”.

The “Coolidge Effect” term was first used by Ethologist Frank A. Beach in 1955 based on an old joke about U.S. President Calvin Coolidge. Apparently, the president and his wife were doing a separate tour of an experimental government farm. At the chicken yard, Mrs. Coolidge noticed that the rooster was mating very frequently. She inquired with the attendant and was told that this behaviour happened dozens of times a day. Mrs. Coolidge said, “Tell that to the President when he comes by.” When the President was given that message, he asked, “Same hen every time?” The attendant replied “Oh, no Mr. President, a different hen every time.” The President responded “Tell that to Mrs. Coolidge”.

The Coolidge Effect has been identified in almost all species, and in some animals (i.e., male rats), the male will continue to mate until he almost dies of exhaustion. In humans, this phenomenon can set the stage for sexual infidelity and a host of problems ensuing from this indiscretion.

2D Structure of Hormone Oxytocin

How can we remedy this problem? First, stop all sexual activity for at least two weeks. Second, avoid sex that aims at producing intense orgasms. Third, sexual encounters should last for as long as possible and include lots of affection/light touch. In this setting, oxytocin (the cuddle hormone) rises at the same rate as dopamine, and the sexual partners are able to experience a combination of excitement and calmness. The good news is that the more oxytocin produced, the more sensitive nerve cells are to this hormone. Therefore, there is no biochemical rollercoaster or Coolidge Effect.

Sex is a fascinating subject – especially orgasm. Although we are awash in information about orgasms, many of us are misinformed. The type of sex that is commonly promoted can have a profoundly negative effect on our overall wellbeing and the health of our romantic relationships.

A complex interaction of neurotransmitters and hormones make orgasm possible, of which dopamine is the key factor. Luckily, there is a loophole in this biochemical rollercoaster/Coolidge Effect, and it is the hormone oxytocin. Mother Nature is wise enough to enable us to both feel intense desire for our partner (dopamine) and deep attachment (oxytocin) so we are able to bypass the dark side of the big “O”.

Literary Truths

Here are other health benefits associated with the hormone oxytocin:

  1. Reduction of cravings: oxytocin helps recover from other types of addictions such as cocaine, morphine and heroin. Also, there are fewer symptoms of withdrawal.
  2. Greater calmness: oxytocin calms the individual and the people s/he comes in contact with.
  3. Faster recovery: companionship raises oxytocin, and people with serious diseases (i.e., HIV positive) live longer and recuperate faster.
  4. Less depression: oxytocin counteracts cortisol (a stress hormone) that is often responsible for depression and anxiety disorders.
  5. Greater sexual receptivity: oxytocin reduces impotence and renders sex more pleasurable.
