Try this simple technic for supercharging your orgasms. Breath control.
When we masturbate we tend to hold our breath when we near orgasm. The closer we get the less we breathe. Do this. Masturbate in your favorite way. Make sure your lying down as I doubt you could stand up during this experience. Then begin to breathe deeply in a connected manner. Deep diaphragm breathing at an average speed being sure not to stop at the inhale or the exhale. Make sure you have at least 20 connected breaths. The effect is like a strong drug. Your stomach and lower abdomin will vibrate like crazy, the sensation is greatly magnified and you'll likely scream uncontrolably, depending on how long you breathe. The faster you breathe the more intense it becomes.
Be cautious, too much speed in breathing can actually make your fingers curl the first few times you do it, but it goes away with experience. This breathing technic has been around a long time and has been studied extensively by Stanisloff Groff of LSD research fame and by those practitioners of Reberthing as well as Buddhist Monks. I don't think they had masturbation in mind, but rather spiritual enlightenment. However, it works great for both, and you get greater, more explosive orgasms.
And when your finished masturbating and you're thanking god for how good it felt, you're in the perfect state of mind, if you choose, to make real contact with your spiritual nature. Although I am not a woman, I am told it is equally effective for both sexes. -MWK
