Heteroflexible was the fastest growing sexuality of 2025 - this is what it means

"Dr Luke Brunning, lecturer in Applied Ethics at the University of Leeds, said of the findings: "For some, heteroflexible 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." Dr Brunning added that the flexibility could be viewed "negatively" as a "deviation" from the heterosexual standard, especially for men who may "suffer extensive bi-erasure" or be "unable to accept they are 'actually gay'"."

"Heteroflexible was the fastest growing sexuality of the 2025, according to a dating app's data. Data released by Feeld - a dating app for the curious, open-minded individuals - has revealed that its members' fastest growing sexuality of 2025 was being heteroflexible. The app shared that the sexuality was the fastest-growing, up 193 per cent, with millennials constituting almost two thirds (65 per cent) of total heteroflexible members."

Heteroflexible membership on Feeld rose 193% in 2025, making heteroflexibility the platform's fastest-growing sexuality. Millennials constituted 65% of heteroflexible members; Gen X accounted for 18% and a further 15.5% figure was also reported. Switching between heteroflexible and straight identities is identified as a common sexuality shift. Heteroflexible describes primary attraction to the opposite gender with occasional attraction to or openness toward same-gender experiences, often framed as a form of bisexuality or sexual fluidity. Some people use the label to reflect current experience or as a promise-to-self to explore future attraction. Flexibility can be stigmatized as deviation from heterosexual norms and can be viewed with suspicion within some queer spaces.
