Ask mom about masturbation

Okay I masturbate, but I don't know if it's a taboo subject in my house because it's just not mentioned. My mom jokes about sex an all that and I know what sex is and everything like that and she knows I know. I'm not old enough to buy porn or sex toys or anything like tat, but I want to try out all those things as I masturbate. How should I ask my mom or any other member of my family, to buy these things for me? I don't have an older brother and my dad dosen'ttrust me to go on the internet, so I don't think he'd buy these things for me. My grandmother might, ther's a very possible chance. A very small chance, very very very very small. I want porn and lube and all that when I masturbate, but I don't know how to get them. Please help???

I also know where my grandmother keeps sex toys and vibraters and lube but I don't want to steal from her. I don't know where my mom keeps anything though. My grandmother is 43. So she's not some old hag or anything.

lPLEASE HELP!!!!

If your mom jokes about sex, you might be able to slip in the casual question, "Y'know, mom, is it REALLY normal for somebody to masturbate? Or is there something wrong with people who do it?" If you like her answer, you can go on to ask (jokingly or seriously) if she'll buy you sex toys. If she kinda says that masturbation isn't a cool topic with her, you can pretend it was just a random question that popped into your head.
