PGAD | Persistent Genital Arousal Disorder

I read about PGAD or Persistent Genital Arousal Disorder today and I was quite surprised that there is a disorder like this. Here are some articles about this disorder:

From About.com:

Persistent genital arousal disorder (PGAD) is a newly described disorder that is not yet fully understood or defined. It refers to the experience of persistent feelings of genital arousal (often described as “pelvic tension”) that are not associated with sexual stimulation of any kind, that don’t go away on their own, and that cause the individual pain or distress.

The disorder was originally called persistent sexual arousal syndrome (PSAS) in the literature. The change in terminology was recommended because strictly speaking the problem is not sexual; it’s a problem with the genitals. While PGAD was first written about in the clinical literature in 2001, it is likely something that has been experienced by women for many years in silence.
