when masturbating a girl, if she starts shaking and beathing really heavy and and kinda twitching and then just stops but wont let u keep rubbing her, is that an orgasm?

It might be, but it also and more likely to be just before one.

his indicates you have to slow down and lighten up. When the sensations get to be too much she wants you to stop - it is too much of a good thing. So as soon as that starts you have to touch very lightly and move very slowly and not stop (unless she tells you to) and hen the sensations won;t be as srong, but sdhe can continue to tolerate teh sensations until she has an orgasm. And then you can increase speed and pressure until it happens again. That is the way a woman can hundreds of orgasms.
