No matter what you plan on inserting (a toy, finger, penis, or favorite vibrator from Amazon), you’ll need to use lube during anal sex to help things ~glide~ smoothly. "The anus does not self-lubricate, and the tissue of the sphincter and the rectum can easily tear with non-lubricated friction," says Cecilia Villero, a pleasure educator and consultant based in New York City.
