Persistent genital arousal disorder (PGAD), previously called persistent sexual arousal syndrome, is spontaneous, persistent, unwanted and uncontrollable genital arousal in the absence of sexual stimulation or sexual desire, and is typically not relieved by orgasm. Instead, multiple orgasms over hours or days may be required for relief. PGAD occurs in women. It has been compared to priapism in men. PGAD is rare and is not well understood. The literature is inconsistent with the nomenclature. It is distinguished from hypersexuality, which is characterized as heightened sexual desire. From Wikipedia
