12 Best Strap-Ons and Harnesses in 2024

Best Overall

• Pros: Supportive and comfortable, compatible with a wide range of toys
• Cons: Next to none—practically perfect

Four experts that we spoke to praised the Joque for its fit, features, flexibility, and feel. “This harness offers great support and is adjustable for different body sizes and toys,” Jennifer Litner, PhD, an AASECT-certified sex therapist and founder of Embrace Sexual Wellness, tells SELF. Carol Queen, PhD, who works at the sex toy store Good Vibrations, particularly likes that its O-ring, which holds the base of a dildo, is made of a flexible elastic, so you can swap in toys of varying widths.

This model comes with two internal pockets for bullet vibes, too. You can stow one vibrator in a pouch above the O-ring to provide a “pleasurable buzz” to the wearer and the person receiving in a face-to-face position, Dr. Queen says. The second pocket can hold a vibrator against the perineum or between the labia, and can stimulate the genitals of the person being penetrated in front-to-back positions like reverse cowgirl.
