I like this, it's so true, not to say I can't get aroused from just the physical, I simply don't stay aroused.
I have never faked an orgasm since bdsm but I will admit to faking the intensity of it. Sometimes a girl is just rundown or whatever, if he's given me his all, I want desperately to give it back, if an intense orgasm is what he wants then I will be a bit more dramatic than how I really feel.
