According to Sexsomnia.info, "Sexsomnia is a newly identified and a rare medical condition where the sufferers engage in sexual behavior during their sleep. Sexsomnia is a discrete alternative of sleepwalking also known as sleep-sex that includes behaviors of sexual arousal with automatic activation (e.g. erection and orgasms.)" So THAT explains it! All those poor fella's I bitch slapped across the face at 2:00 a.m. I thought were just feeling randy; looks as though they had a legitimate medical explanation for their wandering body parts! My bad!
