I'm the same way -- it's a lot of fun for me. :P
He's told me on numerous occasions that physically I pretty much hit all the marks for him, that there's nothing he'd change at all. And I totally believe that due to how much control I have over his sexual mood, LOL.
One fun thing I do sometimes when I feel like getting frisky later is put my hair up while out in public with him. I almost never put my hair up unless I'm about to give him head in the bedroom, so when he sees me do that I can immediately tell where his mind is going and he gets so awkward. :P I've never told him that I know why, either!
I don't think it's bad unless you're using it for malicious purposes like trying to hurt him. I manipulate the shit out of my husband all the time but it's always in a playful way as a means to get him riled up for some kind of sexual activity.
