Sexsomnia, also known as sleep sex, is a type of sleep disorder known as a parasomnia. Parasomnias refer to unusual sensations and behaviors, such as sleepwalking, that people may experience or exhibit while asleep, falling asleep, or waking up. In the case of sexsomnia, people engage in sexual behaviors such as masturbation, sexual movements, sexual aggression, or initiating sex with another person. Though their eyes may be open and they may make sexual noises, they are asleep during these activities and unaware of their behavior once they are awake.

It is difficult for experts to estimate how many people experience sexsomnia. The disorder can occur unexpectedly, and a person may not know they experience it unless another person notices the effects. However, nearly 8% of people at a sleep center exhibited symptoms of the disorder.

Sexsomnia can cause considerable shame and distress for both people who experience it and their partners. However, treatment is possible and may include the use of medications or lifestyle changes, depending on the underlying cause of the parasomnia.

What Are the Symptoms of Sexsomnia?

The symptoms of sexsomnia vary depending on the person, but the underlying feature of this parasomnia is that a sleeping person exhibits sexual behaviors that they are unaware of and unable to control. These behaviors can include:

  • Masturbation
  • Fondling
  • Sexual noises
  • Sexual movements
  • Initiating sexual activities
  • Sexual aggression
  • Sexual assault

Sexsomnia can occur alongside other parasomnias, including sleepwalking and sleep talking. It appears to be more common in men than in women, possibly up to three times more common. Masturbation is the most common behavior in women with sexsomnia.

In addition to the sexual behaviors, signs that someone is acting under the influence of a sexual parasomnia include:

  • Unresponsiveness or minimal responsiveness to conversation or the environment
  • Unusual sexual responses or aggression
  • Inability to be woken, or difficulty being woken
  • No memory of their sexual behaviors once awake

Nocturnal emissions, commonly called “wet dreams,” are not the same thing as sexsomnia. Nocturnal emissions are considered a normal part of male adolescent development and are also experienced by adult men. However, some people with sexsomnia may mistake their condition for nocturnal emissions if their behavior is not witnessed by another person.

What Causes Sexsomnia?

Research into the causes of sexsomnia remains limited, but experts have found that it is associated with a wide range of underlying conditions and risk factors. These include:

  • Other parasomnias, such as sleepwalking and REM sleep behavior disorder
  • Obstructive sleep apnea
  • Sleep-related seizures
  • Kleine-Levin syndrome
  • Chronic insomnia
  • Restless legs syndrome
  • Narcolepsy
  • Persistent sexual arousal syndrome
  • Sleep-related dissociative disorders
  • Nocturnal psychotic disorders
  • Bruxism, or teeth grinding

Parasomnias and Kleine-Levin syndrome were the most common underlying factors in one review of the literature. However, sexsomnia also appears to be closely related to temporal and frontal seizures.

    What Triggers Sexsomnia?

    Not all sexsomnia can be linked to an underlying medical cause. Some cases appear to be brought on by environmental or lifestyle triggers. These triggers may also cause the onset of sexsomnia in people with an underlying disorder. Commonly reported triggers include:

    • Drinking alcohol
    • Past or current recreational drug use
    • Stress or anxiety
    • Sleep deprivation
    • Depression
    • Poor sleep hygiene
    • Shift work

    Sexsomnia triggers also seem to vary from person to person. If you experience this parasomnia, you may discover you have triggers that do not appear on this list.

    How Is Sexsomnia Diagnosed?

    Most people who experience symptoms of sexsomnia do not report them to their doctor or sleep specialist. Shame is a common factor among people with this disorder, but it is important to remember that sexsomnia is often treatable, and medical professionals have your best interests in mind.

    If you are concerned about the possibility that you experience this parasomnia, speaking to a medical professional is the first step in diagnosis and treatment. Your doctor may recommend a recorded sleep study, or video-polysomnography, in order to better understand your condition and any underlying sleep-related causes.

    Depending on the results of your sleep study, other tests may be required to discover whether you have another medical condition associated with sexsomnia.

    How Is Sexsomnia Treated?

    Treatment for sexsomnia depends on the underlying cause.

    For people whose sexsomnia is related to another parasomnia, being prescribed a benzodiazepine may be helpful. Sexsomnia associated with other sleep disorders is usually relieved by treating the underlying problem, such as the use of continuous positive airway pressure (CPAP) machine or a mandibular advancement device for obstructive sleep apnea.  Cases of sexsomnia caused by seizures respond well to anticonvulsant therapy.

    As sexsomnia appears to be caused by a wide range of conditions, your doctor may prescribe treatment options related to your unique circumstances. They may also suggest that you make lifestyle changes to avoid potential triggers and take steps to ensure your safety and the safety of others in your home until the condition is under control.

    Coping With Sexsomnia

    Sexsomnia can be highly upsetting for both the person with the disorder and the people in their life. Since people with this parasomnia are unaware of and not in control of their actions while asleep, they may behave in ways they would never choose to while awake. This can pose serious, distressing complications around consent, as sexsomnia may cause someone to be sexually aggressive or initiate sex with a person they would otherwise not behave sexually with.

    Receiving a diagnosis and appropriate treatment is the first step in coping with sexsomnia. While many people feel shame around their condition, speaking openly and honestly with the people in their life about diagnosis and treatment helps keep everyone safe. Counseling, both for the person with sexsomnia and any others who are affected, can help with the emotional toll this disorder can pose.

    As sexsomnia treatment may not be immediately effective, it is crucial to take safety precautions as necessary. Depending on your situation, this may involve:

    • Sleeping in a separate room
    • Locking bedroom doors
    • Avoiding all known or possible triggers
    • Setting movement alarms, particularly in cases of associated sleepwalking

    It is crucial to have good sleep hygiene, which has been shown to help people with parasomnias. Following a sleep schedule, winding down at the end of the day, and keeping a consistent bedtime routine are all part of healthy sleep hygiene.
