I tell my therapist it is only 3-6 and that it is not really an issue. I am embarrassed, which means I have a problem.
Your therapist probably thinks what you told him is inaccurate.
As a rule of thumb, a lot of professionals believe that when someone tells you how much they do something, if it's a negative behavior, then double what the person tells you.
If it's a positive behavior, cut the amount they told you in half.
