Dean almost purred at the feeling of the hand in his hair. Merlin he loved that. He mumbled something in appreciation against her skin, but her next comment had him leaning back to look at her. He hadn't meant anything beyond what they were already doing, slow, baby steps. He had meant physically, with his hand up her skirt, where he should stop, but he was too dumbstruck by the question.

The genuine surprise on her face was equal parts endearing, amusing and frustrating. Dean thought it categorically unethical that women went into marriage with such little knowledge of sex. Flowery metaphors and lines about duty were all such bullshit. Sure, people in the business of making children needed to do it, but it had every opportunity to be actually fun and satisfying along the way. 

"There's a lot of possibilities actually." Dean was pretty familiar with all of them, too.
