Afifi and Faulkner (2000) investigated instances in which individuals had sexual interactions with their platonic cross-sex friends. 51% of their sample had sex with their friend when they had no intention of pursuing a romantic relationship with them, and 34% of participants noted having sexual relations with their friend on multiple occasions. Within Afifi & Faulkner's study, of those who had sex with their friend, two-thirds stated that it improved their relationship and 56% stated that the relationship did not develop into something romantic.
