A difference between a person's reported experience of arousal and genital or other bodily responses. A bodily response cannot establish desire, enjoyment, identity or consent.

In brief
A body response is information—not permission.
Mind and body do not always move together. Lubrication, erection, flushing or other responses can occur without wanted arousal, while someone who feels interested may show little measurable response. Understanding this protects people from blame and prevents physiology being misused as evidence of consent.
What research measures
Laboratory studies may compare self-reported arousal with measures such as genital blood flow. A meta-analysis found that concordance varies and, on average, differs across participant groups and study methods.
These are group-level findings, not a test for an individual. Context, attention, anxiety, hormones, medication, disability and measurement choices may all affect results.

Read the rest: evidence, law, safety and sources
Subjective arousal
A person's own reported experience of feeling sexually aroused; only that person can describe it.
Genital response
A measurable or noticeable physiological change that may be reflexive and does not reveal intention.
Desire
Interest or motivation relating to sexual experience; it can be present without obvious bodily response.
Consent
Freely chosen, informed and continuing agreement to something specific—not an inference from anatomy.
Reflex does not equal wanting
Bodies can react automatically to touch, pressure, imagery, fear or other stimuli. An unwanted response during coercion or assault does not make the experience wanted and does not transfer responsibility to the person affected.
The reverse also matters: limited lubrication or erection does not necessarily mean a person lacks interest. Communication and comfort are more useful than treating one bodily sign as a verdict.
Consent remains separate
Consent depends on capacity, freedom, scope and continuing agreement. No physical response replaces an expressed and freely made decision, and a previous response does not authorise later activity.
If words and body cues appear inconsistent, pause and check rather than guessing. Uncertainty is a reason to slow down, not permission to proceed.
Clinical context
Persistent or distressing changes in arousal or genital response can have physical, psychological, relational or medication-related contributors. A GP or appropriately qualified sexual-health or psychosexual professional can assess the wider picture.
Clinical assessment should not impose a performance target. The relevant questions include comfort, distress, function, context and what the person wants help with.
Non-graphic examples
What the umbrella may include
Feeling interested while anxiety limits a visible bodily response.
Experiencing lubrication during unwanted contact without wanting it.
Having an erection during sleep without conscious desire.
A medication affecting genital response while subjective interest remains.
Pausing because a partner's words or comfort—not bodily response—are unclear.
