SEXC-5

Triangulation as sexual and relational control

Definition

The deliberate introduction or weaponization of a third party (real or implied) to provoke jealousy, competition, insecurity, or compliance in the sexual and relational sphere.

How it operates

Public and/or private flirtation and attention-seeking, messaging, social media spectacles, and/or emotional intimacy with others. Using a third party's attention to punish or devalue the target. Mocking or pathologizing the third party while simultaneously encouraging idealization. Creating situations in which the target must compete for the abuser's sexual or emotional priority. Creating public humiliation for the target(s). The third-party and the target are both targets of destabilization.

Function

Destabilizes the target's sense of unique value, keeps the target in a state of anxious monitoring, and asserts the abuser's sexual and emotional dominance.

Harm

Systematically erodes secure attachment and converts intimacy into a competitive arena in which the target must continually prove worth.

Why this is coercive control

Transparent, mutually agreed non-monogamy conducted with ongoing consent and equal agency; ordinary social interactions without the competitive or punitive frame. The conduct here destabilizes the target's sense of unique value, keeps the target in a state of anxious monitoring, and asserts the abuser's sexual and emotional dominance.

Constructed example

The abuser maintains highly attentive public exchanges with another woman, posts about her gifts and admiration, then labels her "crazy" when confronted, while accusing the primary partner of "trespassing boundaries" and "disrespecting his space" for noticing the pattern. The primary partner is left questioning her own perceptions while the triangulation continues.

Fictitious. Written to illustrate the behavior. Not a case.

Literature map

Identifying a behavior described here does not establish a pattern of behavior and does not establish coercive control. A tactic is not a regime. The instrument consolidates peer-reviewed literature so a reader can check when in doubt. The instrument is not a coding manual. Carlton Research does not provide the instrument as a weapon.
