Ways to tell a girl is faking during sex?

If it sounds too good to be true it usually is.

What I mean is if it sounds like something out of a porno then she is most likely playing it up for you.

Sorry to tell you.but it's almost impossible to tell by her facial expressions or words if she's faking. I've faked before and we do everything we would normally do to make it seem real. However, something we can't fake. When we orgasm the muscles in our vagina contract rapidly. I'm not sure if guys can feel it. But we can't fake that.

she will be with you.
