Okay I'm getting a little closer. I've been putting anal toys on my wish list for a while and I've narrowed it down to 3 toys. One is glass, one is steel, and one is silicone. After you vote feel free to say if you're choosing based on material, or based on shape or size. What do you recommend? Should I get all 3 since they are different? Or are they so close in size that it would be redundant?
