I find it best if I'm not wet rubbing my clit vigorously. You can get a better grip if that makes sense, I find it takes longer to reach climax when its dripping wet and doesn't give me the best orgasms, its best rubbing in a circle around my clit extremely fast with two fingers sometimes all my fingers so you don't once miss the spot. I can't stop at one I have to go at least 10 times more. The most I've done is 22 in a half hour time span, the more I do the more it makes me feel like I want to squirt cum. By the end of it I'm dripping in pussy juice. Tires me out a lot but its worth it.
It took me a while the first time I did it but now it's easy, takes me about 1-2 mins. Try it its sooooooo good.
