Thanks for query,
is not a countable act.
When you feel desire of it you can go for it.But make sure that excess is always poison.
Frequent masturbation needs more semen to release but as it's production cannot cope up with your frequency you may got less quantity or some times no discharge.
cannot be increased by any means.take healthy vitamin rich food.avoid junk foods.
This is not a disease.you are perfectly all right.Just reduce the frequency of masturbation.Divert your mind when you have desire for it.
