The way that i kind of keep it alittle interesting, cuz my guy is the same, he really wants me to come up with new things...its hard, but its kinda fun once you get the hang of it. like, (ok this sounds cheesy, but hey...lol) I'm a big fan of lingerie, big fan...so is my guy. So randomly, I will go buy a full on outfit. I mean like last week i went and bought a babydoll dress that was black and had the little thigh high straps on them. So I bought thigh highs too. and I got some really cool lace undies to go with it. And wore that under my work clothes. So when I got home. ANd i just plopped on the couch and was watching a movie. He came over to make a move....and suprise suprise he didn't even expect it. Its random, and a little teasing. I do that, or i mean you can buy something like that....and say hey i got you something can you guess what color it is....make it an all day game of where he's trying to guess what you got him... It makes is fun and makes him think about you all day.
There that whole part of the lingerie thing, or you can try little silly things like blind folding him (this is all sensual nothing like sm) and get an ice cube and run it down his neck chest and so forth, but just tease, don't do anything to really get him going. Just brush up against, kinda stuff. Thats what I would do....
I know its lots and i kinda rambled, but hey there is some advice, I hope it kinda maybe helps.....
Good luck!
