Eva is right, as well as the others who have responded. With anything in life you can enjoy it more when you know how it works right? Masturbation teaches us how are bodies work and we can communicate that to our partner(s). That communication then increases emotional connections because you are exhibiting a need and with a deeper emotional connection comes better sex.
