The Pearl at the Gate

This book is totally naughty, like, erotica...shhhhhh! Actually, it read like a traditional historical romance, with a smidge of the Bluebeard tale, and more graphic sex.

Some of the story hinged on the both members of the couple having no idea how kinky the other one was, and they managed to completely miss how really into the BDSM the other one was, but a good time was had by all. The ending was almost Judith McNaught-ish in the big misunderstanding leading to hurt feelings on both sides.
