Is it normal i bite and suck my shoulders and knees?

Ive done this for the past couple of years now, I randomly start biting/sucking my upper arms, the bit where the shoulder meets the arm, and my knees. I end up with slight bruising that look kind of like lovebites and it can be quite awkward. What i want to know, is does anyone else do this/do you think it's normal?

    There was a kid in my grade 7 class that did that to her arm and trust me, you do not want to be that kid.

    If you do this to punish yourself i think thats a problem i do that sometimes and the best advise that i can give you is find better way to harm like run until it hurts or start combat sports its perfectly accepteble for society somehow rather than suspisious cat paw scars on your arm
