Mustache and beard and chest hair have nothing to do with masturbation
. They are dependent on the expression of genes. The genes within you may not have been switched on yet, or your genes are so composed that you would develop only scanty mustaches and beard... the time will tell that.
Whatever the case - not having mustaches and beard need not be a matter of concern, because individual differ in the amount/density and other characteristics of facial hair as well as the timing of its onset. If you have developed pubic hair (hair around the genitals), it is a good indication that your secondary sexual development is likely normal.
