Maybe you have sensitive skin. If you can convince your parents to buy soap for sensitive or acne prone skin that is a start. There is a brand called Murad, they make excellent products for acne and sell acne body wash. If that's too expensive, you can ask them to buy you Dr. Bronners Peppermint Castile soap (works wonders), lastly, there are body loofahs and loofah towels. You can get one for like $6. I bought one in order to exfoliate the skin in hard to reach areas, works wonders. If your parents wont buy either, for $2 in any drug store they sell exfoliating gloves. They are kind of tough. You put them on, soap them up and literally rub your skin. It will feel scratchy but it will take off the dead layers of skin. Be sure to use a good moisturize afterwards (preferably something without any dyes or perfumes in it).
