Being flippant, it would be easy to say that for many women, the main problem with orgasms is not having them frequently enough.
For sufferers of persistent genital arousal disorder (PGAD), however, all the joy is gone from sexual activity when you spend your entire day having orgasm after orgasm without any stimulation necessary.
Cara Anaya-Carlis is one such woman. Carlis, 30, experiences up to six straight hours of sexual arousal every day and can have up to 180 orgasms in a two-hour period.
For Cara, the condition seemed to develop spontaneously three years ago, and she has been living with it ever since. Despite visits to countless doctors and specialists, no cure is forthcoming.
Cara says the condition is ruining her life as the smallest of tasks become an excruciating gauntlet of embarrassment.
