Does porn scar you for life?

At 6 years old I found porn on my dads mobile, and, being a curious boy I watched some. for a while after that I didn't watch much, but when I was 7 or 8 while online I found some porn and I watched it. Again, I gave up watching it until I was about 10 or 11. This was when I decided to try masturbating. To my surprise it worked. All this time it never really bothered me. Now, at 13 I look back at this and I feel like I shouldn't have found it that young. I feel like I was deprived of being innocent. When I think about it I feel unspeakably dirty and sometimes I even feel a little bit depressed. Is this something which could be, to use a terribly overused phrase 'scarring for life'? And how can I take my mind off this? Any help is appreciated:)
