If two heads are better than one, then three heads are better than two, right? Well, that’s exactly the thought process behind a throuple. A portmanteau of the words “couple” and “three,” a throuple is a three-person relationship where all people involved are intimately connected, explains sex and polyamory educator Dedeker Winston, co-host of the Multiamory podcast. (That typically means they’re involved both romantically and sexually, though it’s worth noting that people who are asexual and/or aromantic can be in throuples, too.) Understanding how a throuple works and why people might engage in one can help you figure out if you’d benefit from this relationship structure.
