1st. if you are a minor inform your parents of the situation. Secondly you need to call the police and inform them of the situation and ask them for advice, preferably talk to a female cop if available. Another option is to find a lawyer and go down with your parents, one that specializes in minor sexual harassment.

Inform your parents. Full stop. Be prepared to have them withdraw you from the job, and don't make a scene, either with your parents or the manager.
Keep a paper log with dates and times. Every single day, every little encroachment. Be scrupulously honest.
Under no circumstances allow him to touch you beyond ordinary gestures (shaking hands, shoulder touch, that sort of thing). Maintain a formal, no-nonsense, business persona--no giggling, no ingratiating smiles, etc.
Remember, if you call the police, the situation immediately goes out of your control and you will never get it back.
If you are not in fact being physically molested, your options are limited anyway.
Good luck, and welcome to adulthood.
