I masturbate like 7 times a day is that normal ?

Not necessarily: Not necessarily (not unless all that masturbating is getting in the way of a person's ability to work or to eat healthy meals, is preventing adequate sleep at night, or is not allowing other exercise that all healthy people should be having). As always in life, one should do everything in moderation. Too much of a good thing... can be bad.

No: Seek professional help. This OCD may dominate your life to the exclusion of other activities and may distort your sex life.
