My body, my choice means that the person who owns the body (you) gets to decide what they do with their body. It is important to remember that everyone has the right to make their own decisions, and nobody else should try to decide what someone else does with their own body. Everyone has the right to choose what their body does — for example, if you want to get a tattoo, dye your hair, or do anything else with your body, then it's totally up to you. Nobody else should tell you what you can and can't do with it.
