The Discovery Health Chanel's special Strange Sex investigated extreme sexual disorders and anomalies, one of them being "sexsomnia," which is a form of NREM parasomnia, that causes people to have sex while asleep, and usually not remember it later.
Another disorder featured on the show was a woman who is allergic to her husband's semen, a condition the coupled discovered on their wedding night when they had unprotected sex for the first time. I guess she never blew him before? Or is her vagina just allergic? They didn't go into detail on that.
Frankly, I don't see what the disorder is with this woman. It sounds like she's describing a rather pleasant way to spend an evening.
