I wanna get my cartalidge pierced but my mom wont let me. Do you think its really that big of a deal?

im fourteen btw. i dont think it its that big of a deal but she still wont let me. ive had my ears pierced for like a gazillion years now and they have never gotten infected or anything bcuz i always make sure to clean them and everything. i told her i would take care of this one to but she still wont budge!! let me know what you think. i dont care how old, or gender you are just let me know! thanks.
