Porn insiders actually at times complain they'd like to retire the trope because it can be difficult for performers to get off at the end of a scene, meaning producers have to burn money idling on sets for up to an hour while they masturbate-and because many stars on the receiving end dislike them. Since then, facials have really popped off among porn consumers. These scenes allowed filmmakers to clearly show male porn stars reaching orgasm, and to signal to the viewer: Hey, pal. But facials-the sex kind, not the spa kind-didn't become a well-known thing until adult filmmakers adopted them as the standard ending scene in mainstream porn films in the mid-1970s. Since the dawn of sex, we have to assume that people have been trying to ejaculate on their partners' faces.
