Sure, Lucky Girl!! The one that I am going off about on this thread (in the original post) would probably be a good beginner one... it's not too big, but big enough that you can play with it both on your clit and in your vagina to see what you like. It was $18, about the running price for a starter vibe, though you can get smaller ones for cheaper ($10 is about the minimum).
You may just want a "slimline" vibe though, one that is smooth, to start with... take a browse around some of the women-owned sex shop websites to see what you might like. You can order right off the web and they'll usually send it in plain wrapping. If you live anywhere near Seattle, San Francisco, Chicago, New York, or Boston, all of those cities have really good women-owned sex shops where you can go in, handle the vibes (on display), turn them on, and see if you like the feel of them before buying a new one. Most male-owned shops don't allow you to do that... they just have the vibes in plastic packages on the wall, so they are more hit-and-miss for the ladies.
Here are my two favorite sites to get you started:

Have fun and let us know how it goes!!
