The physiological responses characteristic of sexual arousal (genital and breast vasocongestion and sensitivity) persist for an extended period of time (hours to days) and do not subside completely on their own.
The signs of physiological arousal do not resolve with ordinary orgasmic experience and may require multiple orgasms over hours or days to remit.
These physiological signs of arousal are usually experienced as unrelated to any subjective sense of sexual excitement or desire.
The persistent sexual arousal may be triggered not only by a sexual activity but also by seemingly non-sexual stimuli or by no apparent stimulus at all.
The physiological signs of persistent arousal are experienced as unbidden, intrusive and unwanted. When the feelings of genital arousal persist for days, weeks or even months, they are experienced as personally distressing and worrisome.
