Do people with attention-deficit hyperactivity disorder (ADHD) have a more difficult time being monogamous? Are they more inclined to be in sexually open relationships?

Sex therapist Ari Tuckman just published a book titled ADHD After Dark that explores these questions, as well as how ADHD impacts people’s sex lives and relationships more broadly. For this book, Tuckman surveyed more than 3,000 people who were in relationships in which one partner has ADHD and the other doesn’t in order to better understand when these relationships work—and when they don’t.

One of the things Tuckman’s survey revealed was that persons with ADHD were more likely to have participated in both consensual nonmonogamy (i.e., being in some kind of sexually open relationship) and nonconsensual nonmonogamy (i.e., cheating or infidelity). Persons with ADHD also expressed more interest in having an open relationship compared to their non-ADHD counterparts.

I thought these findings were particularly interesting, so I asked Tuckman what he thought about how persons with ADHD might fare in a consensually nonmonogamous relationship. Below is an excerpt from our discussion (you can listen to our complete conversation in this podcast). Note that this transcript has been lightly edited for clarity.

Justin Lehmiller: You mentioned how persons with ADHD expressed more interest in consensual non-monogamy and also that they had a harder time maintaining monogamy in the sense that they reported having been more likely to commit infidelity. This made me wonder whether polyamory or other forms of consensual nonmonogamy might be particularly well suited to persons with ADHD.

But, at the same time, it could be a double-edged sword. Something like polyamory could be a challenge for people who have time management issues, right? When you have more relationships to manage, that's obviously going to take more time. So I’m curious: do you have any thoughts on that, or any insights into how persons with ADHD might fare in a consensually nonmonogamous relationship?

Ari Tuckman: First of all, I love the fact that you've kind of done a deep dive into this. I think it's an interesting thing and I think that you're absolutely right that, on the one hand, to effectively manage polyamorous relationships requires a lot of communication and coordination. Simplistically speaking, this could be a challenge for folks with ADHD. It's hard enough for them to keep one partner happy, let alone keeping two or three or more happy.

And there is the risk of that sort of hyperfocus, which when you're a kid might be on Minecraft. But as an adult, there's the risk of hyperfocusing on that new, awesomely interesting partner to the exclusion of your older or more familiar partner(s). So that would require much more direct communication. And much more assertiveness on the part of the longer-term partner to say: “You know what, I love the fact that you're having a great time with that new person, but I'm kind of feeling neglected right now. So, I'm not going to yell at you about it. I'm not going to be passive aggressive. I'm just going to speak my words, and we need to make sure that you and I are spending time together as well.”
