An excellent answer.
The only things I would add would be that just like your limbs, heart lungs and brain need regular exercise to remain in tip-top condition, so does your reproductive system, and even sexually active people rarely have sex daily, so masturbation is a great way to maintain the exercise to make up any shortfall.
Also, masturbation is the easiest way to learn how to control your physical and emotional response to sexual stimulation.
Many is the girl who has lost her virginity "accidentally" because she did not understand, well enough, what was happening to her physically and emotionally - things that she would have been better prepared for with adequate masturbation.
Finally, many women only learn how to achieve orgasm through practice during masturbation. Those who never masturbate can sometimes endure a lifetime of unfulfilled sex with an inattentive lover.
