Should I get a vibrator?

I'm a 17 year old female and I've been thinking of getting a vibrator. My idea was to pay a friend and have it ordered to her house as I don't want it shipped to mine. I don't know if that would be something I'd get in trouble for though? (The whole getting a vibrator if anyone even found it.) I don't see why I would. My second idea was to physically get one but I don't know if I'm even allowed in an adult shop.

I've been masturbating since I got my period at 11 and my fingers are fine but I'm looking for something more. What do you guys think? Would I be allowed into a shop? Should I wait?
