Inserting a Butt Plug, or anal play more generally, has the capacity to provoke deep pleasure and relaxation.
In his book, Anal Pleasure and Health, which we strongly recommend, Jack Morin states that you should implement a NO PAIN EVER rule when exploring this form of play. We obey this rule scrupulously.
A great deal of the pleasure of anal play comes from the relaxation of the external anal sphincter, the muscle at the opening of the anus, where we often hold a lot of tension.
If you’re playing with a butt plug, lubricate it and the anus beforehand with a water-based lubricant.
Whether you are giving or receiving or both, listen closely to yourself and breathe deeply.
NEVER FORCE THE BUTT PLUG IN. But rather - KNOCK AT THE DOOR AND WAIT - SEE IF IT WILL OPEN. In this sense the anus is just like the vagina. Never force anything in!
This is a non-goal directed activity. It is about knocking and waiting, as the body yields and opens.
