Sexual fluidity is in the air…or is it sexual flexibility? Earlier this year, dating app Feeld named “heteroflexible” today’s fastest-growing sexuality, citing a 193 percent increase in use of the label among Feeld daters last year.

To identify as “heteroflexible” generally means to consider oneself primarily straight, with some level of interest in queer or same-sex experiences. The Feeld report interprets the rise of heteroflexibility as a sign that “curiosity is becoming culturally acceptable” as young people “experiment at the margins of their existing identity,” suggesting an increasing societal understanding of sexuality as dynamic rather than fixed.

But while heteroflexibility may be having a moment, it’s not a new term. In fact, it may strike some as a bit of a dated throwback to an arguably less sexually fluid era. According to LELO sexpert and certified sex therapist Casey Tanner, the term “heteroflexible” dates back to sexuality discourse of the late-90s/early-2000s, when similar labels like “bi-curious” and “mostly straight” began to emerge. While these terms indicate a degree of sexual fluidity, they may be considered controversial in some circles as they tend to center heterosexuality as opposed to queerness and are often used “to describe fluid experiences without fully abandoning the social safety of a straight identity,” says Tanner.

So what does it really mean to be heteroflexible, and what does the 2020s resurgence of this label say about the current state of sexuality, queerness, and fluidity? Read on for a full rundown of heteroflexibility in 2026.

What Does Heteroflexible Mean? 

“Heteroflexible means you identify as predominantly straight, but are open to the idea of hooking up with someone of the same sex or gender,” explains Zachary Zane, Grindr’s sex and relationship expert.

For some who identify as heteroflexible, that “flexibility” may constitute occasional attraction to people of the same sex or a potential interest in “experimenting” with their sexuality. Others may consider their flexible side more situational, like if someone is only open to same-sex experiences in a group sex setting or other specific contexts.

You might say heteroflexibility is vague by design—a term meant to describe a liminal, loosely defined space—and what it means in practice can vary from one person to another. But essentially, to identify as heteroflexible is to communicate that you’re straight, but “have some wiggle room” under the right circumstances, says sex and relationships educator Melissa A. Fabello, PhD.

Is the Term Heteroflexible Problematic? 

Ultimately, neither the label “heteroflexible” nor the identity itself are inherently “problematic.” As Zane puts it, “If you feel heteroflexible best describes your sexuality, then you should absolutely use it. No one but you should determine how you identify sexually.”

However, it’s worth noting that there is some discourse surrounding the concept of heteroflexibility. “The term can be both useful and controversial, and that tension is important to talk about,” says Tanner.

One of the main issues is that heteroflexible is a term that ultimately describes queerness while centering straightness. Use of this label “raises questions about one’s attachment to straight identity and privilege,” says Fabello. Some may see “heteroflexible” as a way for straight-passing folks to dabble in queer experiences while maintaining the privilege and safety of a heterosexual identity.

“Historically, many LGBTQIA+ folks have rolled their eyes at terms like ‘heteroflexible,’ seeing it as a way for people with privilege to dip a toe into queer waters without standing in solidarity with queer communities,” says Tanner. “Many queer folks understandably feel frustrated when people want the ‘fun’ parts of queerness without recognizing the social or political implications of being queer.”

More specifically, heteroflexibility often faces accusations of biphobia. Fabello notes that most definitions of bisexuality encompass the queer attraction and/or behaviors that some may choose to call heteroflexible. “If you are attracted to multiple genders, you could identify as bisexual,” says Fabello. To avoid doing so in favor of the heteroflexible label may be seen as a choice rooted in biphobia that perpetuates bi-erasure.

“The other controversy is the way in which ‘heteroflexible,’ not unlike ‘bi-curious,’ can land for queer folks,” says Fabello. “In a culture wherein queer people are often fetishized and seen as ‘experiences’ rather than full human beings with their own desires and boundaries, the idea of heteroflexibility can feel akin to being conceptualized as an ‘experiment.’”

Ultimately, however, the experts maintain that everyone should be free to identify as they see fit.

“There’s nothing inherently wrong with saying, ‘I mostly identify as straight, but I’m also open,’” says Fabello. “There’s something powerful and necessary about being honest and authentic in how your sexuality shows up.”

That said, both Zane and Fabello encourage those who identify as heteroflexible to think critically about where that choice comes from. “In a world without homophobia, would you identify as bi?” Zane posits. “Or are you identifying as heteroflexible because you feel like it really speaks to your desires and behavior?”

So Why Is Heteroflexibility on the Rise?

The Feeld report frames the rise of heteroflexibilty as a promising sign that daters today are embracing sexual fluidity over rigid binaries.

According to Tanner, there’s definitely some truth to this idea. “Younger generations are much more comfortable with the idea that sexuality is fluid over time and context,” she says. “We’re seeing more people play with language that keeps the door open for exploration and evolution. ‘Heteroflexible’ fits that mood. It acknowledges variability without forcing someone to squeeze themselves into yet another box.”

On the other hand, the revival of a largely hetero-conforming label may strike some as more regressive than progressive amid our current cultural and political climate. A more skeptical view might see a rise in heteroflexibility as indicative of a retreat back into a culture of compulsory heterosexuality rather than a move towards one of sexual fluidity.

“I don’t think it’s a coincidence that a resurgence in heteroflexible identity is happening at the same time as blatant fascism and other indicators of conservatism,” says Fabello. “While I think many people find freedom in the label, it is worth asking why we feel compelled to stake our claim to straightness in a world where queer (and especially trans) people are actively being persecuted.”

However, Tanner notes that amid this increasingly dangerous climate, the protections a straight-passing identity can provide may feel justifiably worth clinging to. In a moment of intensified backlash against queer and trans rights, “claiming an explicitly queer label can feel more vulnerable, especially for people who are navigating family, workplace, or community environments that skew conservative,” Tanner explains. “For some, ‘heteroflexible’ can feel like a kind of compromise between inner truth and outer safety.”

Ultimately, Tanner sees the rise of heteroflexibility as neither inherently bad nor good, wholly regressive nor wholly liberating. Rather, “I see it as evidence that people are trying to tell the truth about their desires in a landscape where identity, community, and safety are still inequitable based on sexual orientation,” Tanner says.

“Overarchingly, the debate over labels is tired,” adds Fabello. “The truth is, they’re useful up until they aren’t.” In the meantime, “People use the best language available to them to communicate who they are to others, and language can never capture the complexity of human experience.”
