What can go wrong
These are conceptual frameworks, not treatments, so there is no direct physical risk; the caution is against treating any one model as complete. The linear Masters-and-Johnson cycle can pathologize normal responsive desire; over-applying any model risks misframing a patient's experience. Good clinical assessment uses these models to understand context and inhibition rather than forcing a single template.
This is something to take to a clinician. The Atlas can tell you what is known about sexual response models in general. It cannot tell you what is happening in your body, and the difference matters most for exactly the symptoms that bring people to this page.
How sexual response is modeled has evolved from Masters and Johnson's linear four-phase cycle (excitement, plateau, orgasm, resolution) and Kaplan's triphasic model (desire, arousal, orgasm) to Rosemary Basson's non-linear, intimacy-driven circular model and the Bancroft-Janssen dual-control model. Dual control, operationalized in the Sexual Excitation/Inhibition Scales (SES/SIS), proposes that sexual response reflects the balance between a sexual excitation system and one or more inhibitory systems (SIS1, inhibition due to performance failure; SIS2, inhibition due to threat/consequence). This framework integrates Barlow's anxiety findings, explains individual variation in vulnerability to dysfunction, and underpins much modern sexual psychophysiology.
From a linear arousal staircase to a balance of excitation and inhibition.
What people take it for
What it is taken for. Approval, where it exists, covers only some of these.
How it works
The dual-control model posits two semi-independent neurobehavioral systems: a sexual excitation system (SES) responsive to sexual cues, and sexual inhibition systems (SIS1, tied to fear of performance failure; SIS2, tied to threat of negative consequences such as pain, disease, or being caught). Net sexual response is their balance, and people vary on each dimension as measured by the SES/SIS questionnaires. Men high in inhibition (especially SIS1) or low in excitation are more vulnerable to dysfunction, integrating Barlow's attentional findings into a trait-and-state framework. Masters and Johnson's model described observable physiology; Basson's reframed the entry point as intimacy and responsive (rather than spontaneous) desire.
Why the linear model was not enough
Masters and Johnson's cycle was a landmark description of genital physiology but treated desire as a given and response as a uniform staircase, fitting poorly with people whose desire is responsive rather than spontaneous and with the everyday reality of inhibition. Basson's circular model (developed largely from women's experience) made intimacy and context the drivers of arousal and desire. Bancroft and Janssen's dual control reintroduced the brakes: it accounts for why the same man can be aroused in one context and inhibited in another, why anxiety helps some and harms others (Barlow), and why propensity for inhibition predicts dysfunction risk. No single model is 'correct'; they answer different questions.
What people get wrong
Often saidMasters and Johnson's linear cycle is the definitive model of sex
ActuallyIt was a foundational physiological description, but it treats desire as automatic and response as uniform. Basson's responsive-desire and Bancroft-Janssen's dual-control models address its limits.
Often saidLow or responsive (not spontaneous) desire is a disorder
ActuallyBasson's model reframes responsive desire as normal, not pathological. Context and intimacy, not a fixed spontaneous drive, often initiate arousal.
Who profits, and who pushes back
Nobody is named here yet, because we have not done that work on this entry. Read that as unfinished. Somebody almost certainly sells this, and somebody almost certainly disputes it. Assume both until we have checked.
How we got here
William Masters and Virginia Johnson published Human Sexual Response in 1966 from laboratory observation. Helen Singer Kaplan added a desire phase in 1979. Around 2000, two reframings arrived: Rosemary Basson's non-linear circular model (primarily from women's experience) and John Bancroft and Erick Janssen's dual-control model at the Kinsey Institute, the latter operationalized in the SES/SIS scales and integrating Barlow's earlier anxiety research.
- 1966Masters & Johnson, four-phase linear cycle
- 1979Kaplan adds desire (triphasic model)
- 1986Barlow's cognitive-interference model of dysfunction
- 2000Basson circular model; Bancroft & Janssen dual-control model
- 2002SES/SIS scales validated
