Is it normal i cant control my masturbation after like 4-5 days?

When I don't masturbate for some time (4-5 days), I'm filled with fantasies, thoughts and urges to masturbate. I try to control them, but it's just an impulse too powerfull to resist, especially at night/shower.

However, on the first 3 days, I barely even remember when I masturbated. I act normal and feel absolutely no need to do it. But from the 4th day, my brain starts flooding me with fantasies and such.

Do I have something like "compulsive masturbation" or do you think "lasting" 4-5 days is normal?
