Get a thick anal lubricant.
Lube is always a good idea when it comes to anal play, but McCain recommends anal lube specifically.
“Of course, you can use a water-based lubricant, but the thickness of anal lube sticks to the toy better, so you don’t have to apply as often,” she says.
Also, make sure you’re lubing all the beads. “Really coat them, as well as your backdoor, so that you are well lubricated,” she adds. “It’s a tight hole back there that is gripping around a toy, so you don’t want to hit a dry spot that makes you have to pause your fun.”
