The teleiophilic delay is a phrase used in the incelosphere to refer to the phenomenon of the 2000s and 2010s wherein the median age of losing one's virginity, of getting married or forming a relationship are all rising deep into the adult years.
This trend was previously thought to be limited to the western world, but western norms are affecting the rest of the world too. In the past people got married in their early twenties or late teens. The modern trend has seen first-time settling norms go from the latter denarian years, on to the vicenarian years, and gradually heading towards the tricenarian years. Incelospherians usually see this as a negative since it is implicitly treating allosexual young people as if they are asexual, and view this normalization as a possible societal cause of their involuntary celibacy.
