ANAL: Anal Plugs and Tunnels
An anal plug or butt plug is a toy that goes into your anus and stays there while you play, says Sinclair. Yes, it's really that easy to learn how to use a butt plug; there's no thrusting or in-and-out motion happening, but rather a butt plug is intended to provide stimulation just from staying in place.
In addition to being a standard butt plug, you can use the tunnel hole that goes all the way through the plug for various play including lube insertion, fingers, watersports and toys. The clear version also makes it possible to see right into the other person.
