Got any advice

So I want to know some good ways to mastbait (sorry for the grammar and spelling) I have tried the pillow and the shower head for me it doesn’t work or either drys me out to we’re it hurts but I usually use my hands but I feel like I need something more and I can’t have or buy a vibratio because I live in a house with my dad (parents are divorced and I dont talk to my mom asked my sister she said she thinks im not ready to have a toy but I feel like I’m ready and at a somewhat good age)
