to BigEssexGurl :I know what you're saying but most men bang away causing discomfort right away thinking they're doing good. I rather a woman throw the ass back than run. And it's true some women run when it's too good,usually they don't want the guy to know how good he is so he won't get a big ego.
to chamberri :In cases like this, sex for some woman can become too pleasurable that it hurts to continue, and then feel very good seconds later and hurt again, similar to how some men cannot tolerate further stimulation after he cums.
