So why doesn't 'Fifty shades' movie show Ana having an orgasm? For 2 reasons: 1º) Because 'Fifty shades' is not a Sci-fi movie; and 2º) because the point of Maledom is *MALE PLEASURE*, emphasized and asserted by female displeasure and pain
After the somewhere around the 7th orgasm, it stops being fun and starts to become uncomfortably overstimulating. It's around this point that even the sluttier ones start telling us what we want to know.
