Thanks for choosing HCM to post your queries.
You treat a person only if he has an illness. Masturbation
and night fall are a common and normal phenomenon. It doesnt lead to any problem. it just indicates that you have adequate performance of your sexual organs. This thing will get better, with age and you donnt need any medication for the same. Masturbation doesnt cause any problem and it is a myth that it is bad.
Have a nice day.
Hope i am able to solve your queries.
