When we are petting, how do I know my girlfriend had an orgasm?

There is a good chance you won’t be able to tell whether she came. The first physical sign that a girl gets excited is her vagina becoming wet. But this happens already within seconds and doesn’t say much about her feelings. If the arousal increases she can get a sex flush and her nipples can get erect. Her breathing might become irregular and it may look as if she is very warm. But sometimes there are no outward signs of arousal. Whether a girl has come or not is often hard to tell. Reactions differ greatly. Some become very noisy, while others become very quiet. Some girls move a lot and make a rocking movement in the pelvic area, while others grow passive and are even motionless, almost not breathing. But with most girls you feel them shudder when their love muscles contract. Her face might look like she’s in pain. But with women there is no real proof, like ejaculation with men. Girls can easily fake orgasm and many don’t come, even when they are very excited. So the only way to be sure is asking your girlfriend.
