The next time he goes to do anything that makes you feel uncomfortable, tell him NO. Leave the room, or leave the house. He can babysit. Tell your parents why you left. Don't ever do anything that you don't want to. It sounds like you are in a situation that you are not ready to handle, if at all possible don't go back to babysit at all. It's your body, DO NOT let him touch it without your permission.
