When it comes to human psychology, addiction is like quantum physics in that few understand it and Hollywood constantly gets it wrong. I know I say it a lot on this blog, but it’s worth belaboring. People are complicated. One person may watch “Star Wars” and think it’s the greatest piece of cinema of all time. Another may watch it and say it has no redeeming values.

That’s an important context to consider when discussing topics of addiction, which affects a significant portion of the human population. According to Addiction Center, there are approximately 20.6 million people over the age of 12 struggling with an addiction. According to the Centers for Disease Control, over 200,000 people have died since 1999 from prescription drug abuse alone.

Addiction is a serious issue. I know people who have struggled with addiction. I think everybody knows someone in their lives, be they a friend or relative, who has struggled with an addiction of some sorts. Addiction is real and there’s actual biology behind it. As such, it stands to reason that the rising instance of sexual addiction is real.

Before I scrutinize this sexy, yet unsexy phenomenon, I need to preface this by acknowledging that our collective understanding of these issues is still developing. What we consider a psychological dysfunction today may end up just being a healthy variation within the diversity of human thought. That’s why homosexuality is no longer considered a disease.

That context is important to establish because the term “sex addict” has been thrown around a lot lately. It’s not quite on the level of “fake news” or “soy boy,” but it has been cropping up, especially in wake of the recent scandals in Hollywood. Both Harvey Weinstein and Kevin Spacey claimed to be sex addicts after their scandals.

Needless to say, not everybody buys that excuse. Given my propensity to bemoan excuses, I count myself among them. These men claiming that sex addiction caused their deplorable behavior comes off as a pitiful attempt to gain sympathy, trying to paint themselves as sick. It also assumes a lot about the complex nature of addiction.

It’s true that we can become addicted to damn near anything, but it’s not just a matter of one particular activity flooding the pleasure centers of our brain more than others. Alcoholics don’t get the same orgasmic release from a cold beer that a sex addict gets from a quickie in the shower. There are other psychological forces behind it.

Since we can’t yet read the minds of an individual person, we have only a cursory understanding of those forces. However, there is an established criteria for addiction within a medical context. The American Psychiatric Association, describes addiction as follows:

Addiction is a complex condition, a brain disease that is manifested by compulsive substance use despite harmful consequence. People with addiction (severe substance use disorder) have an intense focus on using a certain substance(s), such as alcohol or drugs, to the point that it takes over their life. They keep using alcohol or a drug even when they know it will causes problems.

At the same time, it establishes a clear difference between just being addicted to a certain activity, like sex, eating, or playing World of Warcraft for 29 hours straight, and the addiction caused by drugs. They don’t even call it addiction. They have a more official label called Substance Use Disorder. Their description of this condition is a lot scarier than just someone who has more orgasms than most.

People with a substance use disorder have distorted thinking, behavior and body functions. Changes in the brain’s wiring are what cause people to have intense cravings for the drug and make it hard to stop using the drug. Brain imaging studies show changes in the areas of the brain that relate to judgment, decision making, learning, memory and behavior control. These substances can cause harmful changes in how the brain functions. These changes can last long after the immediate effects of the drug — the intoxication. Intoxication is the intense pleasure, calm, increased senses or a high caused by the drug. Intoxication symptoms are different for each substance.

I bring up this distinction because more than one person has described sex like a drug. In doing so, it’s easier to accept that those claiming to suffer from sex addiction have a real ailment. Sex is a powerful drive that evokes pleasure that some brain scans have compared to heroin. Does it not stand to reason that sex addicts are in the same boat as heroin addicts?

The short answer is no. Sex addicts and heroin addicts are as different from one another as an arm-wrestling contest and an underground fight club. Addiction to heroin has a strict criteria for diagnosis. Sex addiction doesn’t meet that criteria in that alleged addicts don’t respond the same way that those suffering from Substance Use Disorder respond.

According to research done by UCLA, the reactions of those claiming porn addiction did not mirror those addicted to other activities like drinking, smoking, etc. Within that same research, it was also uncovered that sex addiction lacks one of the most important features of an addiction, namely that of diminished response from the pleasure centers of the brain.

That’s key because one of the most damaging factors of an addiction is that over time, the addictive behavior doesn’t light up the pleasure centers of the brain like it used to. That’s why alcoholics need more alcohol and crack addicts need more crack to get the same high. Brain scans show that in drug abuse. They don’t show it in sex addiction.

In fact, the conclusions of the researchers on sex addiction were somewhat mundane. According to the data gathered from the brains and experiences of real people, the idea of sex addiction is nothing more than having a high sex drive and poor impulse control. That’s not an addiction. That’s a personality quirk. If anything, the very term “sex addiction” undermines the suffering of real addicts.

I know those conclusions is not going to convince those who genuinely believe that they’re struggling with sex addiction. I don’t doubt that these people are struggling and it’s negatively impacting their lives, their families, and their relationships. However, I believe putting it in the same category as drug abuse only skews our understanding of addiction and sexuality.

Some people are really just a lot hornier than others. In the same way some people have a bigger appetite for food, some have a bigger appetite for sex. Unlike food, though, those suffering from eating disorders don’t blame the entire concept of food. There are often other psychological factors behind it.

Sex also has another complication that food and eating don’t. Our culture has an established set of sexual norms that idealize some forms of sexuality and shame others. Even though we’ve accepted more diversity in recent decades, we still idealize monogamous romances where those involved only have sex to make babies or explore the kind of passion reserved for a scene in “Titanic.”

As a result, anything that deviates from that narrative, be they an open relationship or just wanting to hump for the sake of humping, is subject to scorn or shaming. I’ve noted the flaws in this sort of narrative before, but on a much larger scale, it creates a situation where certain manifestations of sex become less a variation and more a disease.

Like homosexuality, though, treating those variations as flawed or damaged doesn’t make them go away. It’s possible for a drug addict to get treatment to repair the damage those drugs have done to their bodies and minds. It’s not possible to complete reshape and remold someone’s baseline sexual desires without causing serious damage.

To really get an idea of how this can motivate self-professed sex addicts to engage in such erratic behaviors, imagine for a moment that you’re a heterosexual person in a world where only homosexuality is accepted. As such, you’re expected to enter a homosexual relationship with someone and remain in that relationship indefinitely.

That means you have to ignore or temper your basic sexual desires in order to operate in that society without shame or scrutiny. You have to pretend that the relationship you’re in is sufficient when you know it’s not. Since you can’t turn off your brain or your basic desires, it’s going to mess with your mind and inspire erratic behavior.

It’s for that reason that sex addiction, as it’s currently understood, probably doesn’t exist. I say probably because, as I pointed out earlier, our understanding of sexuality, psychology, and the human experience is still limited. For now, though, our conclusions are fairly simple. You’re not an addict. You’re just really horny and you live in a society that doesn’t afford you the opportunities to explore those feelings.
