It took me YEARS to finally get an O. At first I could only do it myself. Eventually I got him to go down on me. That is the ONLY way I can O from him. I can't O from vaginal sex. Most women can't. You need clitoral stimulation.

I'm no expert in toys - but there is one, is it the rabbit? I can't remember the name. It's supposed to work...there.

Try just getting a cheap-o vibrator but point it right on your clit for a while, see what happens.

Once you figure out how to get yourself off, then you can figure out how to have him get you off.
