Sexsomnia

It’s embarrassing enough to be told that you snore or mumble in your sleep, but imagine being told that you take off all your clothes, moan in ecstasy, and sometimes even pleasure yourself—all without any memory of doing so. This is what happens with Sexsomnia.

Researchers at the Sleep Disorder Center at Stanford University have classified the sexual behaviors that occur during sleep into three categories. The first involves actions that the researchers describe as “annoying,” though not harmful. Cases in this category include sexual moaning loud enough to be heard in adjoining rooms, attempts to remove clothing, and mumbling sexually inappropriate phrases. The second category includes behaviors that are also considered annoying but are, at times, harmful to the person suffering from Sexsomnia. Often, this involves violent masturbation that can cause bruising and soreness the next morning. The last, and most severe, category is for actions that are harmful to others. These cases involve inappropriate and violent sexual behavior.

When confronted, people with Sexsomnia have no memory of their actions and become confused and embarrassed. One case study described a man who was so ashamed of his uncontrollable sexual behavior that he refused to share a bed with his wife and would restrain himself during the night to prevent any inappropriate conduct. But even that didn’t work. According to the researchers, on one particular evening his Sexsomnia desires were so forceful that he not only broke his restraints, but also two fingers.

Most bed partners of those with Sexsomnia find the behavior disquieting and unwelcome. There have even been cases of arrest for sexual battery. Other cases aren’t quite as severe, and the episodes of Sexsomnia may be indistinguishable from sex when awake. One woman didn’t realize that her husband was suffering from Sexsomnia for months. Finally one night, she clued in when she noticed something different about her husband while they were having sex: he was snoring.

Some people think that the diagnosis of Sexsomnia is used to justify inappropriate sexual advances. However, in nearly every case, doctors were able to document abnormal patterns of REM (rapid eye movement) or non-REM sleep, something impossible to fake. The majority of cases also had other psychiatric diagnoses. Fortunately, most patients with Sexsomnia can be successfully treated with psychotropic medications.
