How To Buy A Harness Ready Dildo

Whether you’re about to enter the world of strap-on play or you’re looking for a new harness dildo to add more variety to your strap-on fun, we’ve prepared a buying guide for your convenience! For those who don’t know, a harness dildo is a dildo that’s compatible with a strap-on harness, which is a sturdy and adjustable dildo holder that you can use for pegging or vaginal penetration with your favorite dong. If you’ve recently bought a new strap-on harness and need a dildo or want to switch up your current harness dildo with a new one, you can find plenty in our Harness Dildos Collection.

Strap Ons 101: All About Harnesses and Their Dildos

Strap ons are commonly used for bedroom play among couples of all sexual orientation. You can use them for vaginal and anal play, and some strap-on harnesses come with their own dildos. But, if you’re not satisfied with it, most harnesses allow you to switch the dildo and use other ones that are compatible with the O-ring size of the harness; some harnesses have adjustable O-rings, too, which means you can use even more dildo variations for your strap-on play.

Most harness dildos are designed to look like a man’s member and have a lifelike appearance (e.g., veiny shaft, balls at the base) like the Real Skin Whoppers 5 Inch Dildo and  to give you the most intimate experience possible with a sex toy. From slim and small for beginners to big and bulky for more experienced pleasure seekers, you can find the right harness dongs for your sexual satisfaction. The most important part of a harness dildo–and the trait that makes these dildos stand out from the rest–is the round base. Without the base, you can’t use a dildo with your harness because the circle base is essential to secure the dildo to the harness and keep it in place.

Some dildos double as vibrators so that you can enjoy even more thrills with strap-on sex. The Real Feel Deluxe No.3 Realistic Vibrating 7 Inch Suction Dildo is an example of these realistic vibrator-dildo hybrids that you can use with your harness.

How to Choose the Right Dildo for Your Harness

If you already have a harness and you’re looking for a new dildo, the size of the O-ring needs to be compatible with the toy. Let’s use the Fetish Fantasy Elite Universal Beginner's Harness as an example. This harness has a stretchy O-ring, so it’s compatible with any dildo. (If you want a more versatile harness that can fit any dong, look for harnesses like the Fetish Fantasy one that has a stretchy or adjustable O-ring.)

However, in the case that you don’t have an adjustable O-ring for your harness, you can still find the right dildos for it. For instance, the Sportsheets Vibrating Corsette Strap-On Harness has three O-rings included in the set, and the smallest one is 1.5 inches and can fit a dildo that has an approximate circumference of 4.70 inches (about the maximum size). This Sportsheets harness would go well with a dildo like the Doc Johnson Platinum Silicone Slim 6 Inch Dildo and the Real Skin Whoppers 5 Inch Dildo. For every one inch of an O-ring, add about 2.5-3.5 inches to determine a precise dildo circumference. Keep in mind that you can go smaller than the maximum size, but the dildo needs a wide, rounded base to stay in place when inserted through the O-ring.

To make finding a dildo for a harness even easier for yourself, replace your current harness with the Doc Johnson Vac-U-Lock Strap-On Harness. This innovative strap-on harness from Doc Johnson doesn’t use an O-ring; instead, there’s a special plug on the front that’s meant to hold the dildo in place. Since you don’t have to worry about a dildo fitting through the O-ring, you have more freedom to choose any dildo size, shape, and color that’s compatible with the Vac-U-Lock. You can find exclusive harness dildos that fit the Vac-U-Lock in our Vac-U-Lock Strap Ons Collection.

Strap-On Dildo Tip: You can use a lubricant to make it easier to insert the dildo through an O-ring, especially if your dildo has balls before the rounded base. Lubricants will help you squeeze the entire dildo through the O-ring, balls and all. You’ll also prepare your harness dong for pegging or vaginal play!
