Don't Ask, Don't Tell

Don't Ask, Don't Tell (DADT) is a form of consensual non-monogamy in which partners agree that each may pursue romantic or sexual relationships outside the primary partnership, on the condition that neither discloses what happens in them. In principle the rule runs both ways: no one asks, and no one tells. In practice it is often lopsided, with one partner doing most of the outside seeing and the other actively choosing not to know (Polyamory Dictionary).

DADT is best understood as one point on a disclosure spectrum that runs through every form of open relationship and polyamory. At one end sits full transparency — partners share names, plans and feelings about metamours. In the middle sit partial policies such as "only tell when asked" or a basic heads-up before a date. At the far end sits DADT, where partners deliberately withhold even the fact that an encounter took place (Feeld / Dr. Zhana Vrangalova).

History

The source phrase names a specific U.S. military policy: signed into Department of Defense directive in December 1993, effective February 1994, and repealed on September 20, 2011, after Congress voted to end it and President Obama signed the repeal into law the previous December (Wikipedia). The policy itself had nothing to do with relationship structure — it governed whether gay and lesbian troops could serve without stating their orientation — but its central mechanism, an agreement not to ask and not to tell, transferred cleanly to households negotiating non-monogamy. Writers and educators in polyamory and swinging communities picked up the label as shorthand for arrangements built on deliberate non-disclosure, and it now appears alongside terms like kitchen-table polyamory and parallel polyamory in the working vocabulary of that world (Ready for Polyamory).

How it works in practice

DADT is frequently described as an extreme version of parallel polyamory — a structure where a person's partners lead separate lives and rarely, if ever, interact. Parallel polyamory still typically involves some baseline information, such as knowing a metamour exists and agreeing on safety practices; DADT strips that down further, so that a partner may not confirm whether anyone else is currently involved at all (Ready for Polyamory). Couples who adopt it commonly do so to manage jealousy: not hearing details is meant to remove the trigger, leaving mental space for the rest of the relationship and, for some, for other priorities entirely (Non-Monogamy Help).

Even strict DADT agreements usually retain a small set of non-negotiable terms — commonly around STI testing, discretion in shared social circles, or an obligation to say something if a health risk or a serious entanglement arises — rather than covering literally everything. Where the line sits is set couple by couple, and the same two people may adjust it as circumstances change (Feeld / Dr. Zhana Vrangalova).

Demographics & research

There is no population survey that isolates DADT as its own category; consensual non-monogamy research groups disclosure styles together or focuses on the umbrella practice. The closest available figures describe consensual non-monogamy broadly: in two U.S. samples of single adults surveyed for the Singles in America project, 21.9% and 21.2% respectively reported having engaged in some form of CNM at some point in their lives, while other estimates put current CNM practice in the U.S. and Canada at roughly 4% to 5% of adults (Institute for Family Studies, citing Haupert et al.). A separate 2018 YouGov survey for BYU's Wheatley Institution found 12% of respondents had ever been in an openly non-exclusive relationship, with fewer than one in five Millennials reporting the same (Institute for Family Studies). Within that population, sexuality researchers who write on disclosure describe fully disclosed arrangements as the more commonly reported style, with DADT occupying a smaller share of the CNM population rather than the default (Feeld / Dr. Zhana Vrangalova).

Common misconceptions

A common misreading treats DADT as a euphemism for cheating, or as license for one partner to do as they like while the other quietly disapproves. Practitioners distinguish this from actual DADT: the arrangement requires informed agreement to the rule of non-disclosure itself, entered into knowingly by both people, rather than deception about whether outside relationships are happening at all (Non-Monogamy Help).

A second misconception is that withholding information makes DADT the easiest or lowest-conflict form of non-monogamy. Critics inside polyamorous communities argue the opposite: because consent theory generally holds that a person cannot meaningfully consent to what they have no information about, an arrangement built on structural non-disclosure limits how informed that consent can be, particularly around exposure to sexually transmitted infections or the depth of an outside relationship. For this reason, many polyamory educators and clinicians regard DADT as a weaker form of consent than fully disclosed consensual non-monogamy, and some describe it as more prone to resembling infidelity, ending in dissolution, or collapsing back into monogamy after the secrecy becomes unsustainable (Ready for Polyamory; Non-Monogamy Help).
