1. Finish Your Bathroom Job, If Required
If you are wary that the pressure involved with anal sex may make you want to poop, visit the washroom before you get into the act.
2. Be Careful With The Lube
Silicone lubes are usually the way to go because of their thick consistency.
3. Penetrate Gradually
After using a lube liberally, use the tip of fingers, a toy, or penis to stimulate and relax the opening of the anus, to prepare it for penetration.
