How do females know when to stop mas*urbat*ng?

Can anyone who really knows and can give good explanation help me. Here's the question tell me the differences in the mas*urbat*on of a female and male ? How long can I male mas*urba*e for and female and when does a female stop mas*urbat*ng? Like a man would stop after he cums.

Men take, on average, 2.5 minutes to come. Women take about 12 minutes. But the variation from person to person is pretty big, so those figures don't really mean much.

And are you *serious*? When do women stop?! Dude, we stop when we org**m!! In case you don't know what happens then, we get wetter just before and, at org**m, the muscles of the vagina contract about 2 or 3 times and we feel really, really good. I promise, when it happens, you will notice.
