Position affects a number of seriously important aspects of sex, from angle of penetration and range of motion to who has active control over the action. If you've ever raised your hips a bit and suddenly your top started making some serious noise or if you've ever just lifted your leg the tiniest bit and your bottom started to squeal with delight, you understand just how big an impact position has on the quality of your sex.
A simple change in posture can mean the difference between hitting just the right spot and just hitting randomly. Anyone who's ever had even half-way decent sex knows that position is everything.
