Too much porn can wreck your sex life, warns Thai doctor (video)
Expert cites global study linking screen habits to sexual problems
A prominent Thai forensic medicine expert has sounded the alarm over the dangers of excessive porn consumption, warning that it may lead to erectile dysfunction and serious relationship issues, especially among younger men.
Associate Professor Dr Weerasak Charuschaisri, a medical lecturer at Srinakharinwirot University, took to Facebook to share a video clip titled Watching too much pornography can lead to erectile dysfunction. Posting under the name Dr Moo Weerasak, he backed his claims with global research and urged viewers to take the issue seriously.
“Many people may not realise that watching online pornography can affect our sex lives, but research shows that excessive viewing is linked to sexual dysfunction, particularly among adolescent males.”
Citing a 2021 global study published in JMIR Public Health and Surveillance, Dr Weerasak said researchers surveyed 3,419 men aged 18 to 35 and found those who frequently watched large amounts of porn had a 70% higher risk of developing erectile dysfunction compared to occasional viewers. The study also linked porn overuse to premature ejaculation and an inability to reach orgasm.
“Watching too much porn overstimulates the brain and dulls the response to real-life sexual interaction. Men who consume excessive porn often find it difficult to become aroused or respond to real partners.”

But the damage isn’t just physical. Dr Weerasak warned that heavy porn use can increase stress and anxiety, fuelling psychological problems that make real-life intimacy even more difficult.
He listed key signs of porn-related sexual dysfunction:
-
Lack of interest in real-life sex with a partner
-
Difficulty ejaculating or maintaining arousal
-
A compulsive urge to watch porn that interferes with daily life
As for treatment, Dr Weerasak suggests a porn detox.
“Taking a 90-day break from pornography can help restore sexual function. It gives the brain time to reset and re-sensitise to real-life stimulation.”
Dr Weerasak’s post has since sparked wide discussion online, with many praising the doctor for highlighting an issue that is often ignored or misunderstood in Thai society, reported KhaoSod.
Experts say further public education is needed to address the effects of digital habits on mental and sexual health.
