Brit LOL I can't believe you said that!!! I'd be floored if my W ever admitted that much that she liked me taking charge.
In our relationship she gets a little twinkle in her eye, and acts postively delightful when I show the right amount of assertiveness. It's like she can let her guard down, relax, and even be girly knowing that she has a strong man by her side.
You calling him hot, and playfully playing like that must have probably gotten his head spinning in a good way. That's good, tone it down for now, unless he shows that he wants to hear more. (you'll know because he'll take charge more.)
Call me simple, but I think us men if we like a woman and she rewards our actions with interest we'll keep doing them again and again.
I think guys want two things from our partners to be desired sexually, and to be appreciated for who we are. (or in this case for who we are becoming). I think if you can meet these needs for him, no woman in the world has a chance.
