Cum on face points to the finish of a scene, where the climax lands on a partner's face rather than elsewhere. In gay material it is often grouped with the more general term facial, which carries much the same meaning, while cumshot covers any visible finish without specifying where it goes. Since the term describes only the ending, it says nothing about what leads up to it, and related words like blowjob or bareback refer to separate things entirely. Bareback, for instance, is about condom use rather than a distinct act.
