How could I give myself a hanging wedgie without my underwear rip ? - how do you give a hanging wedgie

I wish myself a hanging wedgie. I want a lot of pain and is very high. I do not want to display. Where can I do that? Therefore, I would like to tear my clothes. RIP If I buy new equipment. Put the problem is that I'm only 12 years, and I can not go into the store and only buy underwear. My parents say if I go into the store. My parents see me. How could I buy underwear? Have an idea?
PS no one lives in Canada, Quebec, wedgie Laprairie How do you like me?
