How can I get the most powerful orgasm while masturbating?

Try yoga positions called 'hip openers', and try an herb called dong quai. Orgasms also tend to be stronger when you're ovulating and when you're extremely turned on, so set up a whole evening of whatever gets you horny rather than just grabbing your vibrator and going to town. And if you don't have a vibrator, woman you should go buy one right now. It's gonna be your new favorite thing.

As for squirting, it's an individual thing, but for many women it's easier on successive orgasms, as in you don't stop at the first orgasm, you keep going. It's often more of a pushing feeling than a clamping down feeling, if that makes sense. For me it really doesn't change the feeling of an orgasm, it just makes you wish you'd put down a towel.

Squirting is just urine.

If you are turned on by the idea of wetting yourself when you reach orgasm, go ahead and try.
