Try a small drop of what is called "viva cream." it feels amazing, kind of like menthol. It's also a lot of fun. I am addicted to my vibrators too, so I try not to use them more than a couple times a month, and b.O.B. (battery operated boyfriend) is my only partner right now!!! Imagine how difficult that is.
Anyway, my advice is try the cream with your partner. My guess is that you get off clitorally rather than vaginally. If you don't know, then you have the fun task of playing with him until you find out. Some women are able to get off both ways, but from what I understan, it's pretty rare.
At any rate, keep us all posted.
Ps
try watching porn for some new ideas. You can either watch it together, or alone.
