For a first toy, I'd probably pick a more gentle-looking shape. I was fine with a hard toy at first, but it was the Pure Plug (like a really smooth strawberry-shape). Also I'm kind of against putting lower-rated materials in there, I stick to glass, metal, and silicone for anal toys.
That says TPR Silicone, which I believe is fairly flexible. If you're looking for a hard toy, I think something like the Emerald Explorer looks best (it's $25 and glass).
I'm looking for a comparison between this and say the softer silicone anal toys (ie. "butt hungry").
The Love Pacifier Teardrop IS made from silicone. Antipova just published a review on it and even did a flame test to make sure. Just so you know.
It really depends on what you like, firm pressure or gentle stimulation. Harder materials allow you to feel every bump, ridge and rib from a toy while softer materials, while you can still feel them, are not as intense.
I tend to stay away from cheaper materials, I like them to last and being able to better clean them is a big plus for me.
