Dont worry about it mate, you will find most of us are nice and willing to help and give advice on here rather than just ridicule and mock newcomers, and to answer your question yes you have tore the skin on your knuckle because of not using gloves, i would let it heal up first then get some gloves and get back into it, it might be a little painful to hit the bags now even with the gloves so it might be a good idea to wait till you heal up.
