Vibrators!

Hey there! I'm 15 (16 this August) and recently I've been getting a bit sexually frustrated (being a virgin and all), I've been desperate to buy a vibrator but not only do I know if it's legal but I'm not sure how to do it discretely enough. I'm known for worrying a lot so I'm worried about whether my bank or mum etc can see that a bought it.

My family is also a problem, there's quite a lot of us and my little sister is fond of opening my mail then closing it up again thinking I don't know she does it.

If anyone can help with this, answer my questions and/or recommend any good vibrators for easing you into it. I'd be extremely grateful!
