In brief
Sexual response is variable within and between people. Desire may be spontaneous or emerge after welcome stimulation; genital changes can occur without desire, and desire can occur without obvious genital response. Arousal non-concordance is why bodily response must never be treated as consent.
Older linear models can be useful descriptions for some experiences but do not define a normal sequence. Response can pause, repeat, change direction or not include orgasm.
Context, safety, privacy, novelty, fatigue, stress and relationship dynamics can alter response without indicating disorder.
Interest or motivation, which may precede activity or develop responsively in a wanted context.
The person's felt experience of being sexually engaged or excited.
Physical changes such as erection, lubrication or blood flow, which may not match subjective arousal.
One possible peak or release; it is neither inevitable nor required for pleasure or completion.
Automatic erection, lubrication or orgasm can occur during unwanted stimulation and does not prove desire, enjoyment or agreement. Equally, a person may feel desire without the expected physical sign.
Consent comes from freely communicated agreement and remains withdrawable, regardless of involuntary body response.
Hormones, pregnancy, ageing, disability, illness, pain, sleep, alcohol and medicines can affect different parts of response. Effects may be temporary, situational or persistent.
A new or troubling change deserves a broad assessment rather than assumptions about attraction or relationship quality.
Goal pressure can narrow attention and increase anxiety. Communication can focus on comfort, curiosity and what is wanted now rather than achieving a particular bodily outcome.
Stopping, changing activity or enjoying closeness without orgasm are valid outcomes. Nobody owes visible arousal or a performance.
