Relationships and sex
Women with Epilepsy and Sexual Relationships | Epilepsy Foundation
Many people with epilepsy have fulfilling relationships with a partner. However, epilepsy may affect relationships for some people, and problems with sex are common for both men and women with epilepsy. There are various ways to manage these problems and find support. Seizures are a physical symptom, but having epilepsy can mean far more than the physical impact of seizures, for the person with epilepsy, and their partner. Many people manage seizures well, but seizures can be unpredictable, frightening or shocking, both for the person having seizures and for those who see them. It may be hard to deal with the memory of a seizure, what the person with epilepsy looked like, how you both felt, or with the fear that it might happen again. Some people may not want to be alone with their partner in case they have a seizure, or fear being in the same place where it happened before.
Epilepsy and Sexual Relationships
As many as two-thirds of people with epilepsy face some change in sexual desire, behavior, or activity as a result of their seizures. Even if this kind of problem has affected you, you may not have discussed it with your doctor or someone else who might provide real support and help. Doctors often are reluctant to bring up such intimate topics up in the course of a visit, and many patients do not feel comfortable talking about sex. Whatever the reasons behind the silence, there is no need to suffer. The most common change is a general lessening of sexual interest and activity, sometimes called hyposexuality.
Sexual relationships are a normal part of healthy living. Three things lead to sexual activity: first there is desire -- wanting to have sex with a partner. When that feeling is strong, there is arousal -- the physical feeling that you "need" to have sex. Finally, there is orgasm -- the height of physical pleasure during intercourse.
