A look at “Interdependence and Sexual Health: Relationship factors associated with sexual behavior among sexual minority males in non-monogamous relationships who use drugs” by Tyrel J. Starks, Joseph R. Hillesheim, Juan Castiblanco and Demetria Cain (2026)
Most sexual health research treats people as solo decision-makers: one person, one choice about condoms, one risk. But for many gay, bisexual and queer men, sex happens within relationships, sometimes open ones, and decisions about sexual health are often made together. This American study looks at how the quality of a relationship shapes those shared decisions, particularly when drugs are part of the picture.
What they found
The researchers worked with 192 cisgender gay, bisexual and other men who have sex with men, aged 18 to 35. All were in relationships with non-monogamous agreements, all were HIV-negative, and all had used drugs in the past month. Participants completed questionnaires and a detailed day-by-day account of their sex and drug use over the previous 30 days.
The headlines:
- Relationship quality matters. Couples who saw their relationship as close to their ideal, and as low in “costs” such as conflict and sacrifice, were more likely to engage in joint coping: working together as a team on HIV prevention. In turn, joint coping was linked to less condomless sex with casual partners.
- Context matters too. Condomless sex with casual partners was more likely on days when men had condomless sex with their main partner during group sex, and less likely on days when they had it one-on-one.
- Drugs were part of the picture. Cannabis use was linked with more condomless sex on the same day. Other drug use was linked with condomless sex with casual partners, partly through group sex settings.
The authors’ takeaway is that sexual health support for queer men in relationships should involve both partners, strengthen relationship quality and teamwork, and address substance use, rather than focusing only on individual behaviour.
A grain of glitter ✨
This is a sophisticated study with a valuable focus on couples as a team. But some context helps.
It frames condomless sex largely in terms of HIV risk. In an era of PrEP, the HIV prevention pill, and “undetectable equals untransmittable”, condomless sex isn’t automatically high-risk, and the authors acknowledge that their measures didn’t fully capture PrEP use. The sample was a specific group: young, HIV-negative men who use drugs, mostly from the north-east US. Data collection was disrupted by the COVID-19 pandemic. And while day-level data is powerful, the authors note it still can’t establish what causes what.
Why this matters
If you’re in an open relationship, your sexual health is something you and your partner(s) can genuinely tackle as a team, and a strong, satisfying relationship seems to make that teamwork easier. If drugs are part of your sex life, you deserve non-judgemental support to think about what feels right and safe for you. A good therapist will meet you with curiosity rather than lectures.
Teamwork makes the dream work, especially when you’re trotting through the same meadow.
