Hi, Beth! I think the one you chose would be a good starter toy honestly. It's a fair price, it's waterproof and looks stylish, and it's made by a company that makes high quality toys. It's simple enough to get pleasure from and also a good starting point because after you use it, you'll see how you react, how your body reacts, and then you can kind of use that to make a decision of what to get next.
It's all about experimentation and finding out what you're comfortable with. If I'd seen this vibe as a choice for my first toy, I'd have grabbed it, because my first vibrator SUCKED. It was as loud as a jet engine and the plastic actually peeled off. It was a nightmare.
Good luck, hun!
