Do I masturbate too much?

i am in my teens and all i do is masturbate. i love britney spears she is the one i masturbate to. i do it like 3-4 times a day. like i have a million pic of britney on my laptop so i'm always looking at her. she is so addictive to look at and the i get from her is crazy. i love brit and masturbating to her but is it too much?
