This is the projected outcome of what happens when people try to live out the fantasy of 50 Shades of Grey and it couldn't be any more true. 

People's expectations on sex have been skewed over the last decade a great deal. Things like sexy fantasy books like Fifty Shade of Grey or Porn videos have given a wildly false sense of what most sex is really like. Porn and sex books leave out all the guilt, shame and embarrsment that coems with thinking our side the box in the sex world.

Never does a normal couple transition from one position to the next without pulling a hamstring. Also not everyone is always on the same page when you try to pull out the big guns. I'd say this is a fair assessment of what really happens when people try to make fantasy a reality.

PS: That woman is totally wrong, ninjas are ALWAYS sexy.
