Sex addiction: Signs, symptoms and side-effects
Sex is a natural part of human life, but sex addiction can destroy your life. 6-8% of adults are believed to have a sex addiction, but the condition is still not recognised by the NHS or the DSM-5 (a medical guide doctors use to identify and classify mental health conditions). Thousands of people in the UK are struggling with sex addiction, and if left untreated, it can have disastrous consequences for relationships, well-being, and even your health.

What is sex addiction?
Sex addiction is when you feel compelled to chase sexual experiences even when they are causing damage you can see but can’t stop. Some people think that sex addiction means a high sex drive, but this is often only part of it. Addiction means you are trapped in a pattern of destructive behaviour where sex provides no lasting satisfaction and makes underlying issues worse.
Sex addiction is also known as hypersexuality and “compulsive sexual behaviour disorder (CSBD)”, a term recognised by the World Health Organisation. It often coexists with pornography addiction and sometimes with love addiction, which can make diagnosis and treatment more complicated.
What are the stages of sex addiction?
Sex addiction usually starts small, with early behaviours like excessive porn use or using sex or masturbation to cope with anxiety, loneliness, depression, or boredom. These activities trigger a rush of chemicals in your brain that make you feel briefly better. Your brain then starts linking sex with emotional relief, and previously occasional sexual behaviour becomes your automatic response to any negativity in your life.
But just as you can build a tolerance to alcohol or drugs, you can soon need more frequent sexual activity or more extreme content to feel the same way. This may mean that “regular” porn stops working, so you move to hardcore material, or that occasional hookups are replaced with more risky encounters.
Once addicted to sex, you spend hours every day thinking about it, planning it, or engaging in sexual behaviours while everything else in your life falls apart.
Recognising sex addiction signs
It can be a little scary or embarrassing to admit you may have a sex addiction, but it is nothing to be ashamed of. The important thing is to overcome any addiction denial as quickly as possible, so you can get the help you need. Here are some sex addiction signs that can help:
- Sexual thoughts dominating your daily life
- Multiple unsuccessful attempts to cut down on porn, masturbation, or sex
- Needing harder porn, more frequent sex, or riskier sexual situations to even briefly satisfy you.
- Having to constantly delete messages, sneak around, or lie about money or whereabouts to hide sexual activity from loved ones.
- Time spent on sexual pursuits affecting work, school or family life.
- Sexual activity becomes your main way of managing stress, anxiety, depression, or isolation.
- None of this damage is enough to change your behaviour.
Why is sex addictive?
Sex addiction is a behavioural addiction like gambling addiction or shopping addiction. It takes control of your brain’s reward system, just like alcohol or drug addiction, but through behaviour rather than substance use. Sex triggers chemical releases that create good feelings, but if you do this repeatedly, especially when stressed or upset, your brain treats sex as the answer to any difficult feeling.
Here are some other factors that increase the risk of sex addiction:
- Shame driving the destructive cycle of sex addiction because you feel too embarrassed to get help
- Possible chemical imbalances in the brain
- Constant availability through porn, “hook up culture”, prostitution, and dating apps
- Co-occurring sex addiction and mental health (thought to be present in 88% of cases), and using sex to cope with difficult symptoms
- Early sexual experiences, including sexual assault and trauma
- Loneliness, isolation, or a lack of real human connections or romantic or sexual partners
Sex addiction side effects and dangers
The dangers of sex addiction are often not taken seriously, but they can be enormous:
What does sex addiction recovery involve?
Recovery doesn’t mean never having sex again, but rather developing a healthier relationship with sexuality.
There is no traditional detox stage as required with drug or alcohol addiction, but a period of initial abstinence is important and will likely need professional support. Behavioural rehab provides this support and then different types of therapy to identify which specific behaviours must stop, which need boundaries, and which are healthy to keep.
Ideally, rehab programmes should combine both evidence-based therapies like CBT and trauma-informed therapy and holistic therapies like mindfulness and meditation. You should also look for one-to-one therapy sessions and group sessions, because both together often provide the most important breakthroughs. Not all rehab centres offer this, and many centres don’t treat sex addiction at all, so you may need to shop around a little.
After rehab, you need to take steps to stop yourself falling back into old behaviours once you are no longer in the safety of residential care. If you choose a rehab centre that offers aftercare, alumni services and relapse prevention planning, these can help a lot with adapting to home life again. You can also look for local support, like ongoing therapy and Sex Addicts Anonymous meetings.
