We like surprises in our erotica. The sexy librarian is smart and reserved, but, unexpectedly and under certain circumstances, her wild side is awakened. Her strength is in her sexuality.
This made me start thinking about what would be surprising in a man. We expect the hero to be strong and powerful, so a vulnerabilty may surprise us and make him more human. And how delightful it is for the heroine when his vulnerability turns out to be his uncontrollable desire for her own sweet self. Which makes her feel more attractive and dynamic.
Her sexuality is her strength, and his sexual feelings make him vulnerable--one enhances the other.
Exercise:
What other kinds of surprises are sexy? Make a list. Use at least one in a scene.
