PSAS, identified and named just six years ago, remains a mysterious condition that thousands of women wish they didn't have. They are constantly on the edge of orgasm regardless of time, place or circumstance.

ABC News spoke with four women who all experience unwanted sexual sensations. Heather Dearmon, Nancy Austin, and two women who requested anonymity (referred to as Lauren and Emily) all suffer from unintended sexual arousal.
