Persistent Genital Arousal Syndrome PGAS is a rare disorder that makes sufferers sexually aroused sometimes to the point of orgasm , without any feelings of sexual desire. Unsexual situations—like driving a car, attending a business meeting or going to the movies—can make a person with PGAS highly uncomfortable as they try to hide the feeling of arousal they can't help but experience. While there are many people who suffer from the condition, Zara Richardson may have the worst case of PGAS ever documented or, at least, she's got the most public case of the disorder. Richardson has been known to orgasm up to times a day. While some people think that sounds enjoyable, Zara is not one of them.
