Harness Compatible Dildos

O-Ring Sizes and Compatibility

• In fact, even O-rings with 1.25 inches in diameter can control a dildo with a 3.9-inch circumference. 
• An O-ring with 1.77 inches in diameter will fit a dildo with 5.5 inches in girth. 

Harness Styles and Comfort

• Jock-style harnesses have two straps each weaving through your two butt cheeks. These are extra tight and give you lots of control over your movements and the dildo. 
• G-string harnesses have one strap running between your butt cheeks, similar to g-string underwear. This one makes the dildo feel a bit heavy, but also makes you accurately aware of its location. 
• Body harnesses wrap around your waist, thigh, chest, and genital area. 
• Underwear harnesses look similar to briefs or boxers but have straps extending from them. They are usually non-adjustable so you have to get the right size. 

Types of Strap-Ons & Harnesses

Realistic Dildos

• Realistic dildos imitate real penis by having a distinct head, veins, and testicles. The suction cup is attached right below the testicles.
• Appeals to lesbians, transgender, and non-binary people as they can create the illusion of having a real penis. These types of dildos are available in various skin tones. 

Double-Ended Options

• Made for both partners to share each end and move against each other while keeping the harness adjusted and well-fitted. 
• With two insertable ends, the middle of the dildo stays snug inside the harness and strap with the thigh strap specifically keeping it tight. The 

Pipedream Products Double Delight is a good example of this. 

G-Spot and P-Spot Dildos

• The head of the harness-compatible G-spot and P-spot dildo is bent enough to exactly hit the sensitive spot inside your vagina or prostate. 

Some like the Strap On Me Multi Orgasm also tend to be super flexible and attach to the harness with a magnetic clip instead of a flared base meant to go into the O-ring.
