Common types of anal sex toys include butt plugs, anal beads, prostate massagers, and anal vibrators. Butt plugs are generally small and designed to be inserted and left in place for a period of time, while anal beads are typically longer and have a series of beads that gradually increase in size for heightened pleasure. Prostate massagers are curved toys that are designed to stimulate the prostate gland, and anal vibrators are toys that provide a vibrating sensation for added stimulation.
