Sexual activity has a long and creative history of being described and referred to by slang and euphemism. But when the source domain of the euphemism--the "literal" meaning--is an equally ordinary everyday action, the ambiguity creates problems of interpretation. And in a field like the study of historic same-sex relations, where there is a long tradition of going to some contortions to deny even the scraps of available evidence, euphemism has long been interpreted selectively depending on the genders of the participants.
