I'm confused at your guys comments. Every girl i've slept with has made lots of loud noises like that, and yes even said stuff like "ohhh my goood youre huge".
I think she was acting somewhat because "Ramon" was limp dicked the whole time and was never able to get any sort of rythym going.
Even with boring girls who just wanna lay back and do jack shit, they still end up screaming and kick their legs in spasms by the end of it.
And to the guy who said that women don't like sex. Well that applies to a certain portion of the population. But the vast majority of women want to fuck just as badly as we do, but they won't just screw anything that looks half decent.... like we do.
