Inflatable butt plugs can be used on yourself, or on a partner. These can be used to stretch the anus more, or they can be set up for delivering the most intense pressure and stimulation you never thought was even a possible! Any user can choose the primary size their body can accommodate. Made from either TPE, rubber or silicone or a combination of these materials, there's something suitable here for everyone.
( Always Play safe: do your research and/or seek medical advice if needed, before you engage in a new or unknown sexual activity. )
