People have different opinions about Masturbation. Some people tell about the disadvantages of masterbation, while some tell about its benefits.
Very few people like to talk openly about masturbation. Some people accept only half the incomplete information read or heard about it.
Nowadays most of the youngsters are aware of fitness. They do weight training, CrossFit, Cardio etc. to fit themselves.
Even after doing all this, if a man's body is not growing, he starts thinking that due to masterbation, the body is not growing.
In the gym where I go for workouts, some people have good growth in their muscles, while some others do not see growth. Others often ask them to do less masterbating. However, many times they even speak jokingly in friendship.

Everyone's sexual appetites vary. Just like if someone is hungry for 2 roti, then 4 is hungry. Therefore it would not be right to say how many times masterbation should be done. If still someone does masterbation twice a week, this can be true. But if someone's appetite is high then doing it 1 time daily can also be correct to some extent.
