Anchor butt plugs took their name from their shape: two curved arms like an anchor that press gently against the walls from inside and help the plug stay in place, depending on design and fit. Compared to a classic cone plug, the anchor offers a fuller feeling and a more stable fit. Stability differs by product and does not mean every model is suited to walking around or extended wear.
You will find flexible silicone models for beginners, inflatable versions with a bulb for those who want to control the fill, and vibrating designs. Start with a small size and plenty of anal lube. For anal use choose a truly wide base that cannot pass into the body, never force it and stop if there is pain or numbness. Discreet packaging.
