If you are going to use anal beads, get them in silicone. It feels so much better than jelly, and a lot smoother than the hard plastic beads. These beads are completely covered in silicone, so there's no flimsy strings to break or get dirty. This doesn't mean they are not flexible though, because the TPR silicone bends and flexes to the body without breaking. I've had a few anal beads before, and these are definitely my favorite because they are easy to use, feel great, and are easy to clean. The balls get larger as you stick them further in, so the pleasure increases to your liking. If you haven't already tried anal beads, save the headache and start with these.
