Han is a healthy young man who spends a lot of time in space. The likelihood that he'll be agreeable to a second go round is high, provided that he has a little bit of time to rest inbetween. This young man in particular is fond of this particular lady and happens to want to accommodate her if he can - he just wouldn't nescesserily assume she was interested in a repeat performance without her telling him.

When he's had a few seconds to catch he breath, he makes a point of telling her he enjoyed himself. "That was nice." He murmurs, as he rubs a bead of sweat away from his brow with a lazy swipe of his hand.

He figures the fingers in his hair could be a kind of wordless permission to stay pressed against her for a while. She's warm and feels good, so he doesn't see any particular need to hurry.
