Let's see here...

Get naked. Lay down on a comfortable surface. Spread your legs. Now, feel around down there until you feel something akin to a squishy prune. Rub that. A lot.

Post pics and stories of results. Yes, this is a requirement of all women masturbating.

And, ummmmmmmm...think of me. It'll help. I promise.

((All right, in all seriousness, I agree with Mittimer. No one can really tell you how to get yourself off. Just try things and see what works))
