A psychological and/or physiological response associated with sexual attention, meaning or stimulation. Subjective excitement and genital or other bodily responses may align imperfectly, and neither proves desire, pleasure or consent.

In brief
A response, not permission.
Arousal can involve attention, emotion, genital response, heart rate, muscle tension and other changes, but these do not form one reliable consent detector. Bodies can respond automatically, subjectively or inconsistently in wanted, unwanted and neutral situations.
Several systems, not one switch
Sexual arousal involves attention, interpretation, emotion, autonomic responses and genital and non-genital changes. Context and the meaning of a stimulus can alter the response.
People differ in which changes they notice and how reliably those changes align. A narrow performance model may turn ordinary variability into anxiety.

Subjective arousal
The person's reported sense of sexual excitement or activation.
Genital arousal
Physiological changes such as erection, lubrication or blood flow; these may occur without matching subjective experience.
Desire
Wanting or motivation. Desire may precede, follow or be absent from arousal.
Consent
A freely chosen agreement—not a bodily measurement. Arousal and orgasm cannot supply consent.
Arousal concordance
A meta-analysis of 132 laboratory studies found that self-reported and genital measures of arousal were correlated imperfectly, with substantial variation across participants and methods.
Laboratory measures simplify real experience and do not diagnose an individual. The evidence supports asking the person rather than inferring their experience from one bodily sign.
Consent and unwanted response
Reviews document that genital arousal and orgasm can occur during forced or non-consensual stimulation. Such responses do not show that the experience was wanted or consented to.
This distinction can be important after assault: an automatic response is not responsibility, enjoyment or betrayal by the body.
Health and context
Stress, pain, medication, illness, hormones, sensory conditions, relationship context and expectations can influence subjective or bodily arousal. Desire and arousal concerns are therefore assessed in context.
Persistent unwanted changes or distress may warrant clinical discussion. Commercial products should not promise to correct complex arousal concerns without appropriate evidence.
Non-graphic examples
What the umbrella may include
A bodily response occurs without subjective excitement.
Subjective excitement occurs with little noticeable genital response.
Desire develops after welcome arousal begins.
An automatic response occurs during an unwanted experience and does not imply consent.
Medication changes arousal even though emotional attraction remains.
