Chivers and colleagues  found that men's and women's concordance was more similar when thermography was used as a measure of genital sexual arousal than when VPG was used. Exactly what makes a person feel as if their level of desire is "low" or "problematic"? In older women, decreased pelvic muscle tone may mean that it takes longer for arousal to lead to orgasm, may diminish the intensity of orgasms, and then cause more rapid resolution.
He muses that perhaps, as time passes, a partner may not be as attentive or affirming. Vaginal photoplethysmography VPG can measure changes in vaginal blood volume or phasic changes in vasocongestion associated with each heartbeat. Other people may see it as more of an innate pole, but I see it as something that emerges.
