I'm 20 & I do no have any beard on my face.Slightly on chin.but I have hair on chest. Please give me solution...
Does masturbating reason for this problem?

There is simply no relation between two . Beard , hair on chest , head , and other things are controlled by genes and hormone secretion . You are still 20 , there is nothing to worry . I have seen guys turning 25 and still waiting for their first shave .
