please help me

So I want a vibrator, it's either that or I'm tempted to lose my virginity. I don't want that because I don't want to do it recklessly. Really I could just masturbate with my hand like everyone else but I'm bored of that. I found a small bullet vibrator online at lovehoney.com and I want to buy but I'm obviously underage (17) and I'm nervous about using my card to purchase I don't want something bad to happen. And what if my mom gets to it in the mail before I do? Im worrying a lot but I also want to do it because I'm "the perfect child" and I kinda just wanna SEE if I could get away with it should I buy or no?
