I masturbate and i am mormon, iin?

Okay well, it all started when I was 13 and I felt the pleasure when one of my stiff one rubbed against my bed at night, and so I rubbed it some more until I masturbated. I have never been able to stop since then, and I am a mormon. I've never really felt guilt from it, except just a tiredness I've never really gotten over. I masturbate 4-5 times a week, sometimes more. I don't want to confess to anybody and even my dad told me it's normal. But I just keep getting the feeling that its wrong. Is it just my religion? Should I really confess to someone? Oh, and I've never masturbated to porn. My fantasies is enough, if I started looking at porn then I'd really feel guilty. Does anyone have answers for me or similiar stories? is it normal???
