Identify the valve and external base
Confirm both parts before considering size or features.
Look for a base that stays outside
Choose a design intended for anal use, with a base or retrieval feature that keeps it from slipping inside. Review the photos from the side and base. See Planned Parenthood’s sex toy safety guide.
Read the exact manual
Locate the air release in the maker’s instructions and check it off the body. A vibration switch may not release air. Avoid any model with unclear release directions or a damaged valve.
Stop if it is uncomfortable
Do not force the device or treat the listed expanded size as a target. Stop for pain or bleeding. If the device cannot be released or removed, seek medical care promptly.
