Is it normal that i enjoy pain in a non-sexual way?

Ever since I was a kid I have enjoyed certain types of pain in a non-sexual way. I really like dull, throbbing pains. Sometimes when I was a teenager I would put my finger on my chapped lips, or press on my bruises just to feel the pain. Obviously, there are some types of pain I don't enjoy, like sharp and sudden pains. Is this normal?
