Odette de Crécy avait ce don de ramener Charles Swann à de meilleurs sentiments (le mec était d'une jalousie maladive) en lui chuchotant à l'oreille: "Faire Catleya"
Talking dirty does not have to include swearing. Besides the only word that I can think of that is used in 'talking dirty' that may be considered swearing is fuck. In the context of sex, that can hardly be considered swearing. And 'bad language' is always relative to the situation and the context. I've never really understood the phobia people have regarding certain words. They're just collections of letters after all.
