The Fastest-Growing Sexuality Is Big With Millenials

As we’re closing in on the end of 2025, dating app Feeld has collaborated with Dr. Luke Brunning, a lecturer in Applied Ethics at the University of Leeds. Dr. Brunning also specialises in Philosophy of Love, Sex and Relationships.

At a time when LGBTQ+ rights are being questioned and demonised, Feeld reveals the heartening news that people are still exploring their identities despite the aggressive pushback.

This is true across Gen Z, Millenials and Gen X and the dating experts say that our gender and sexual identities are becoming ‘rapidly more flexible’.

The fastest-growing sexuality on Feeld this year is ‘heteroflexible’ with a 193% increase in members identifying as this, and, according to the dating experts, switching between heteroflexible and straight is one of the most common sexuality shifts.

Their data reveals that Millennials constitute almost two thirds of total heteroflexible members, Gen Z was next at 18% and Gen X at 15.5%.

Feeld say: “The explosive growth of heteroflexibility suggests curiosity is becoming culturally acceptable, especially among younger users.”

Dr. Brunning suggests that some identifying as this may want to dig a little deeper saying: “For some, heteoflexible will describe accurately how they experience attraction or typically behave.

“For others, it might be more of a promise-to-self, something they want to look into further, explore, or which they hope they will be in a position to experience in the future.”

He also suggests that while this offers some freedom, some may still face criticism, saying: “For some, any ’flexibility is a deviation from the heterosexual standard, and will be judged negavtively; particularly for men who suffer extensive bi-erasure.

“For others. perhaps those firmly within the queer community, heteroflexibility may be viewed with suspicion, as indicative of a reticence to be open about somebody’s ‘true’ bisexuality, for example. Or as evidence of internalised homophobia.”
