As far as embracing your sensuality goes, I'd suggest this is primarily an attitude. I don't recommend being flirty with your H right now because he's likely to see that as pursuit.
In my experience confident women, comfortable in their skin, no matter what their looks, are very attractive. When they feel good about themselves, they radiate. It reflects in the way they walk, the way they smile and they have a general openess that is very winning.
I suggest you start by re-building your confidence and think about a dance class to help you ground yourself in your body. There are some good resources out there to help women get in touch with their 'inner goddess', I imagine Seattle might even be one of the better places for it, lol.
I'm suggesting you do this for you, to feel more comfortable with yourself and don't focus at all on your H. Believe me if you get that open, confident walk that says 'here I am', the gentle twinkle in your eye that says 'I like myself and I'm not sure you can handle me'and an open smile, he'll notice without you having to say a word to him.
