I think most sex shops are R18 or R21 and won't let you in. Besides, you won't get any judgments on ebay because know one can see you.
Having sexual urges at 14 is normal, even for a girl. Keep doing what you're doing and wait till you're in love to have sex.
For now, master the clitoral orgasm. Use the tips of your index and middle fingers and rubs in circles. You can also "milk" your clitoris by taking it between your thumb and index finger. Use grapeseed oil as lubricant.
Here's a diagram of your external clitoris:

Your clitoris is a the top of your vagina. When it gets "excited", it swells with blood, gets bigger and comes out from under your clitoral hood.
When it gets really excited, it gets even bigger and retracts under your clitoral hood. That means you're getting close to orgasm.
When you orgasm, you'll feel contraction around your clitoris, vagina and anus.
