The French language has a number of exotic-sounding, suggestive words that have made their way into English usage. There's tryst, which is a meeting between lovers. When something might be a bit rude, you could call it risqué. And then there's the boudoir. A boudoir is not necessarily a bedroom (this is generally called a chambre à coucher), but can be either a private salon adjourning a bedroom or the bedroom itself.
