Understanding the Impact
By Chris Jones
In earlier articles in this series, we explored the concept of deceptive sexuality through the metaphor of the secret sexual basement. We examined the two behavioural systems that define deceptive sexuality within the DST model:
- Compulsive-Entitled Sexuality (CES) – the behaviours occurring inside the basement
- Integrity-Abuse Disorder (IAD) – the behaviours used to keep the basement hidden
Having established those foundations, we now turn to the next part of the model: trauma. If DST stands for Deceptive Sexuality Trauma, the question naturally follows: What is the trauma caused by deceptive sexuality? What impact does this dynamic have on the intimate partner, and on the family system?
Before going further, it is important to acknowledge that discussing trauma can be difficult — particularly for those who have experienced it directly. The impacts of deceptive sexuality can vary widely, and no two individuals experience them in exactly the same way. The goal here is to outline some general principles that help us understand the traumatic impacts that commonly emerge.
In this article, we will begin with an overview of two key types of trauma that often appear in cases of deceptive sexuality: acute trauma and complex trauma.
A Brief Look at the Evolution of the Field
To understand why this discussion about trauma is so important, it’s helpful to look briefly at how the treatment field has evolved.
When the concept of sex addiction was first introduced, partners of individuals identified as sex addicts were often labelled codependent. Their responses following discovery — anger, distress, hypervigilance etc. — were interpreted as evidence of their unhealthy relational patterns.
This idea came largely from the alcohol addiction field. In that addiction context, co-dependency refers to a relational pattern in which a partner or family member becomes overly focused on managing, rescuing, or stabilising the alcoholic, often neglecting their own needs. This dynamic unintentionally enables the addiction by reducing the natural consequences that might otherwise motivate change.
When the alcoholic enters recovery, the co-dependent dynamic can become problematic because the partner may struggle to relinquish the caretaker or control role that developed around the addiction. As the alcoholic begins taking responsibility for their own recovery, the relationship may destabilise because the old roles and patterns that organised the relationship no longer function.
This means that the co-dependant partner has their own work to do – they need to focus on their own recovery and “stay in their lane” (i.e. stop trying to control the addict).
Unfortunately, when this framework was applied to partners of “sex addicts”, it meant that their reactions were therefore pathologised. Fortunately, a major shift has gradually occurred in the field. Instead of viewing the partner’s responses as signs of co-dependency, clinicians began to recognise them as trauma responses. This shift was both important and necessary.
The reasoning for the shift is fairly straightforward. If the sexual behaviour was hidden (because of the system of integrity-abuse behaviours that we’ve identified), the partner likely had no (or very little) knowledge of it. In that case, it is difficult to argue that the partner developed co-dependent coping strategies around something she did not know existed. It’s rather more obvious to acknowledge that the partner has experienced a traumatic event because of the discovery of this hidden reality. Recognising the partner’s experience and responses as being trauma-based rather than signs of co-dependency therefore represents a significant step forward.
The DST model proposes a further step in this evolution. Not only should the partner’s experience be understood through the lens of trauma rather than co-dependency, but we must also recognise the abusive dynamics involved when a secret sexual reality is maintained through deception and manipulation. This is where the concept of integrity-abuse becomes so critical.
Understanding deceptive sexuality as both traumatic and abusive allows us to develop a clearer picture of the partner’s experience and, importantly, what effective treatment and relational justice might look like.
Types of Trauma
Coming back to our main topic now, and the two principal types of trauma that we need to consider: acute trauma and complex trauma:
Acute Trauma
Acute trauma is what most people think of when they hear the word trauma. It is often associated with Post-Traumatic Stress Disorder (PTSD) and generally involves a sudden or overwhelming event — for example, a car accident, a violent incident, or exposure to war. In the context of deceptive sexuality, discovery of the secret sexual basement can function as such an event.
When the hidden reality is suddenly revealed, the partner often experiences what can feel like a profound collapse of reality. The relationship she believed she was in is revealed to be fundamentally different from the one that actually existed. The collision between these two realities can be an acutely traumatic experience, which we could liken to a psychological car crash.
Another important factor is the attachment injury involved. In intimate relationships, partners often function as each other’s primary attachment figures — the person we turn to for safety, comfort, and support. When the person who was meant to provide safety becomes the source of harm, the traumatic impact can be even more severe.
This combination — the collapse of reality and the attachment rupture — can produce a powerful acute trauma response, with PTSD-like symptoms.
Complex Trauma
While acute trauma often occurs at the moment of discovery, it is equally important to recognise the potential role of complex trauma. Complex trauma develops when a person is exposed to repeated patterns of harm, with a consistent theme, over an extended period of time, particularly when they lack a viable escape route or are in a disempowered position. Within the DST model, we refer to this as complex trauma shaping.
If acute trauma can be compared to the impact of a car crash, complex trauma is more like drops of water onto a rock. No single drop causes noticeable damage, but if it continues over a significant period of time, the rock is gradually shaped. In this metaphor, the rock represents the human psyche. The repeated drops represent ongoing patterns of harm – subtle but persistent – that result in the psyche gradually being shaped. Think of a child who is neglected by their parents, or somebody that experiences racial discrimination throughout their life – there isn’t necessarily a specific acute traumatic impact, but there can be a significant complex trauma shaping over time.
Complex Trauma and the Secret Sexual Basement
When we apply this idea to deceptive sexuality, the connection becomes clear. Earlier in this series of articles, we described Integrity-Abuse Disorder as a system of behaviours that covertly control and harm the partner. These behaviours include things like deception, gaslighting, omission of critical information, manipulation, and relational neglect. If these behaviours occur repeatedly over time, they fit closely with the definition of complex trauma:
- They form a repeated pattern of harm
- They share a consistent theme (protecting the secret reality and the abuser)
- They occur over prolonged periods
- The partner is disempowered because she lacks access to the truth
The disempowerment in particular is a very important concept to understand within this dynamic. Because the secret sexual basement is hidden, the partner doesn’t have access to the information necessary to make fully-informed decisions about her life – including the choice to be in the relationship in the first place. In that sense, her ability to escape the harmful situation is compromised.
When the secret sexual basement is hidden, she is in a relationship that she would likely choose to not be in if she were to know the truth. In that way, the intentional hiding of that truth takes away her ability to make that decision. Similarly, she may be engaging sexually with her partner based upon that false reality – would she be consenting to sex with her partner if she knew he was also sexually active with others?
Trauma Before, During, and After Discovery
One important implication of this framework is that trauma may occur before discovery, during discovery, and after discovery.
Before discovery, it is easy to assume the partner is unaffected because she does not yet know about the hidden behaviour. In reality, if deception and manipulation are occurring, the relationship environment may still be shaped by subtle patterns of harm.
To visualise this, consider the image of the secret basement again — but this time picture poisonous fumes slowly escaping from it. The partner doesn’t know that the basement is there, but the fumes emanating from the basement are still poisoning the people in the home above.
These “fumes” might include:
- Emotional withdrawal or relational neglect
- Avoidance and lack of connection
- Gaslighting or subtle reality manipulation
- Moments when suspicions arise but are dismissed
Each of these experiences can function like drops of water shaping the rock.
Then comes the exposure phase, when the secret basement is discovered. At this point the metaphor shifts dramatically. Rather than fumes escaping from below, the entire house collapses into the basement beneath it. This collapse represents the acute traumatic injury caused by discovery.
However, the trauma story doesn’t end there. If integrity-abuse behaviours continue after discovery — through partial disclosures, trickled truths, defensiveness, blame-shifting, minimisation, or stonewalling etc. — then the partner may continue experiencing complex trauma shaping, even after the sexual acting-out behaviours themselves have potentially stopped.
This is a crucial point. A person may stop engaging in the sexual behaviours associated with the basement, but if IAD behaviours continue, the partner still experiences a significant lack of safety within the relationship. When safety is absent, the conditions for ongoing trauma remain.
Looking Ahead
Understanding deceptive sexuality trauma requires us to consider both the acute shock of discovery and the long-term shaping effects of ongoing deception.
Historically, the field moved from labelling partners as codependent and started recognising their reactions as trauma responses. The DST model invites us to continue that evolution by recognising the abusive dynamics inherent in deceptive sexuality and the complex trauma that can arise from them.
In the next article, we will begin exploring these traumatic impacts in greater detail. Specifically, we will look at the trauma reactions and responses partners may experience and examine how those reactions are still often misunderstood or pathologised.
By understanding these responses more clearly, we can move closer to compassionate, trauma-informed care for those affected by deceptive sexuality.
