A growing number of people around the world are identifying with a sexual identity known as heteroflexibility, which has recently been described as the fastest-growing sexuality according to data from a popular dating app’s annual report. This trend reflects shifting attitudes toward how people understand attraction and challenge traditional labels.
What does heteroflexible mean ?
At its core, heteroflexibility refers to individuals who identify as predominantly heterosexual but open to occasional same-sex experiences, attraction or curiosity. It differs from bisexuality, where a person consistently experiences attraction to more than one gender. Heteroflexible people tend to see themselves as “mostly straight” while acknowledging flexibility in how they connect with others.
A trend growing faster than other identities
Data from the 2025 “Feeld Raw” report, published by the dating platform Feeld, shows that the number of users identifying as heteroflexible rose by around 193 percent over the past year. This surge makes heteroflexibility the fastest-growing sexual identity on the platform for 2025. Analysts suggest that this growth is less about a strict category and more about people seeking labels that reflect their personal experiences with sexuality.
Millennials and geography
The report also found that millennials make up the largest proportion of people identifying as heteroflexible, with Generation Z and older generations following behind. Cities such as Berlin were highlighted as having especially high levels of identification with the term.
Fluidity and personal identity
Experts note that heteroflexibility captures a wider range of experiences, from people who are mostly attracted to the opposite sex but have occasionally felt same-sex attraction, to those who describe themselves as curious or open to experiences outside traditional categories. Some people use the term as a way to articulate attraction without fully adopting broader labels like bisexual or pansexual.
Conversation and complexity
While the rise of heteroflexibility has been welcomed by many as an example of evolving understanding of human sexuality, it has also sparked discussion. Some critics argue that it can overlap with established identities, raising questions about visibility and representation. Others see the trend as reflecting a broader cultural shift toward acknowledging sexual fluidity and personal nuance in how people identify themselves.
What it tells us about today’s attitudes
The growing use of the heteroflexible label suggests that more people are willing to explore and articulate their sexual experiences outside rigid binaries. It highlights a generational trend toward openness, curiosity and personalised identity and underscores how contemporary understandings of sexuality continue to evolve in response to lived experience.
