How Porn Can Literally Change Your Brain — and Is Now Increasingly Tied to Erectile Dysfunction
Americans are turning to pornography in record numbers, with recent data highlighting a dramatic surge in online adult content consumption. In January 2024 alone, Pornhub reported over 3 billion visits from U.S. users, once again cementing the United States as the world’s largest source of traffic to the site.
U.S. porn consumption hits record highs in 2024, raising alarms about mental health, brain function, and relationship intimacy, experts warn.

The unprecedented accessibility of porn in the digital era has transformed how people explore sexuality. Yet mental health experts caution that this level of screen-based stimulation may come with unexpected psychological and neurological consequences.
Marriage and family therapist Danielle Sukenik offered insight into these impacts, outlining the complexities of excessive porn use in a recent analysis published by The Conversation. According to her, the intersection of high dopamine release and constant stimulation can disrupt the brain’s reward system and influence real-life behaviors.
An estimated 40 million Americans frequent adult websites on a regular basis, with over 28,000 users engaging at any given moment. This trend extends well beyond adults. Research conducted by Common Sense Media in 2023 found that 73% of minors aged 17 or younger had already viewed online porn, with the average age of first exposure clocking in at just 12 years old.
Pornography’s influence on the brain is becoming increasingly apparent through scientific studies. A landmark 2015 study observed that men who frequently consumed porn exhibited reduced gray matter volume in areas of the brain responsible for motivation and decision-making. These same individuals also displayed decreased sensitivity to sexual stimuli, pointing toward the neurological effects of desensitization.
Repeated viewing of explicit content triggers a rush of dopamine, the brain’s primary pleasure chemical. Over time, this repetitive stimulation forces the brain to adapt, often resulting in the need for more extreme content to achieve the same level of arousal. One 2016 study found nearly half of participants reported watching types of porn they initially found unappealing or even repulsive.
According to Sukenik, this behavioral shift stems from the brain’s diminished capacity to derive satisfaction from standard stimuli, pushing users to seek novelty regardless of their original preferences. In many cases, this desensitization bleeds into users' personal lives, affecting their ability to enjoy physical intimacy with real-life partners.
Clinical research has documented the ripple effects. A 2020 study reported that 23% of men under 35 who regularly viewed pornography experienced some degree of erectile dysfunction when with a partner. These men also took significantly longer to climax, suggesting a disconnect between screen-based and real-world sexual cues.
Such issues don’t stop in the bedroom. Relationships can suffer from diminished emotional intimacy, lower levels of commitment, and increased infidelity. Sukenik points to emotional detachment and erosion of trust as frequent outcomes in partnerships strained by problematic porn use.
Beyond relationship challenges, regular consumption of porn has been tied to worsened mental health. Studies indicate that frequent users are more likely to report depressive symptoms, anxiety, and a lower quality of life than those who abstain.
Adolescents may be particularly vulnerable. Sukenik warns that teenage brains are still undergoing critical developmental changes, making them more susceptible to long-term impacts. A 2021 study found that over 20% of student respondents who consumed porn compulsively experienced severe to extremely severe levels of depression, anxiety, or stress.
Evidence also suggests early exposure can heighten the risk of personality disorders, impulsivity, and rule-breaking behavior. Research involving nearly 11,000 European teens showed a clear link between porn exposure and increased aggression, risk-taking, and even substance abuse.
Still, experts acknowledge that pornography is not inherently harmful. For many adults, it serves as a tool for self-discovery, education, and even enhanced intimacy. Masturbation, often accompanied by porn, has been associated with reduced stress levels, improved sexual awareness, and overall psychological relief.
Some couples report positive experiences when watching porn together. A 2021 study revealed that partners who engaged with explicit content jointly experienced higher levels of sexual satisfaction, improved communication, and stronger emotional connection compared to those who watched separately.
