Ultimate Strap-On O-Ring & Dildo Guide - Honour BlogUltimate Strap-On O-Ring & Dildo Guide

Strap-On harnesses are a great way to add novelty, excitement, greater intimacy and mind-blowing orgasms to your relationship. The two most popular dynamics for strap-on sex are girl-on-girl strap-on sex and girl-on-guy strap-on sex - otherwise known as pegging. Strap-ons can be used by men who want to play around with something other than what they were born with too! Regardless of who is doing the thrusting, one thing is for certain - pegging is getting more popular by the day and at Honour we’re here to make sure you have the ideal harness and dildo to rock the night away.


Strap-On Harnesses

The main type of strap-on is an o-ring harness and dildo set-up, which includes a harness (in either a thong-back or jock style) which uses snap fasteners to secure in place an o-ring. The o-ring is used for securing the dildo of your choice, which you slide through the o-ring before attaching it to the harness. The great thing about o-ring harnesses is that you can swap the o-ring for a different size in a matter of seconds, allowing you to choose any dildo from your arsenal depending on the situation.

Most Honour strap-on harnesses come with a steel 45mm diameter o-ring as standard, which will fit all dildos with a girth of 5.5” (~14cm) or less, but to facilitate dildos with a larger or smaller girth, you can also purchase compatible o-ring sets made in metal or silicone. Metal o-rings are sturdier than silicone, but silicone rings can stretch allowing greater still versatility with your harness.

If you’re looking for a completely adjustable harness set, you can also purchase Honour’s Deluxe Leather Strap-On Set, which comes with 5 adjustable metal o-rings measuring 7cm, 6cm, 5.5cm 5cm, and 4cm in diameter, and also has a second optional o-ring which you can add for support if your dildo is particularly long, heavy, or drooping.

If you are hoping to purchase a dildo and harness together, it is helpful to know which dildos are compatible with each harness and o-ring size. This can involve some maths; so to make it easier, we’ve picked some of our best-selling harness dildos along with their corresponding necessary o-ring size, so you can be sure you will receive a full working strap-on set.


Dildos for 3.5cm O-Rings

O-Rings of 3.5cm and under are for using with our least girthy harness-compatible dildos. We recommend these dildos for pegging or anal beginners especially:

Doc Johnson Anal Starter - 6”

If you’re new to anal play and pegging, the 6” Anal Starter dildo by Doc Johnson is the perfect place to start. Made of soft, jelly silicone and measuring just 3.5” in circumference, this dildo is one of the smallest o-ring compatible dildos from American sex toy juggernauts Doc Johnson.

European Lover Small - 6”

This realistic dildo is a great starter dildo for any o-ring harness play, with a veiny shaft and pronounced glans for extra stimulation either vaginally or anally. This dildo is made of firmer silicone, meaning your new appendage will not droop during strap-on use.


Dildos for 4.5cm O-Rings

Most O-Ring harnesses will come with a 4.5cm O-Ring as standard, making these dildos the most strap-on friendly of the bunch:

Fun Factory Boss Dildo - 7”

The Boss by Fun Factory is a deeply satisfying dildo for vaginal or anal strap-on use, made of smooth, firm silicone and measuring 7” in length and 5.5” in girth. A great dildo for regular users of penetrative sex toys, the slight curve can be angled for either g-spot or p-spot stimulating strap-on sex.

Basix 6.5” Suction Cup Dildo

The Basix 6.5” dildo is made of soft jelly silicone, making is particularly suited to anal play but is also fulfilling when used vaginally. Dildos with moulded balls such as this one are when the second optional support o-ring on our Deluxe Leather Strap-On Set comes in handy to prevent your dildo from drooping and ensures your new appendage will stay where you want it to no, matter how vigorous you get. We recommend using a 4.5cm diameter ring on the shaft, and a 5cm diameter ring over the suction cup for ultimate support.

Easytoys Suction Cup Dildo Black

The Easytoys Suction Cup Dildo is a rock-solid staple strap-on dildo, a great all-rounder with 7.5” of insertable length. Made of smooth silicone and gently-curved for g-spot or prostate-stimulating strap-on sex.

If you’re looking for a dildo with a bit more to offer with your 4.5cm o-ring harness, you can also take a look at The Fun Factory Bouncer Dildo with internal oscillating weighted balls for added stimulation, or the Fun Factory Tiger Dildo, which is curved and ribbed with emphasised ridges for eye-rolling strap-on playtime! You can also take your pick from any of our dildos measuring up to 5.5” in girth.



Dildos for 5cm and Up O-Rings

If you are an experienced strap-on user who enjoys the sensation of playing with large toys, you’ll want to use o-rings with your harness measuring 5cm, 5.5cm, 6cm or even 7cm in diameter. These o-rings are to be used with our largest strap-on compatible dildos.

Doc Johnson Thick Blush Dildo - 8”

Another Doc Johnson favourite, the Thick Blush Dildo is 8” of jelly silicone that won’t disappoint. The moulded balls on this dildo act as the flared base for the o-ring to sit on, keeping your dildo in place. At 5.65” girth, the Thick Blush Dildo requires an o-ring of 5cm to be compatible with your o-ring harness.

Doc Johnson American Bombshell B7 Tango

Not for the faint of heart, the Doc Johnson B7 Tango can be used as a dildo or butt plug, and has a girth of 7”, needing a 6cm diameter o-ring to keep it attached to your harness! The B7 Tango is a challenge for all but the most experienced users.

Toy Joy Prince Charming Royal 8.5” Dildo

This dildo has an eye-watering girth of 6.25” which combines with its impressive 8.5” length to create a perfect strap-on dildo for anyone looking to kick their strap-on sex up a notch! You’ll need a 6cm o-ring over the shaft of this dildo to keep Prince Charming in place.

Doc Johnson Dick Rambone 17” Dildo

The Dick Rambone has a whopping 17” length making it the perfect harness extension for those who enjoy extra deep anal play. You’ll need a 7cm diameter o-ring for this giant dong, and use of a second supporting o-ring will be useful to keep such a monster toy erect!



Hints and Tips

When choosing a dildo to go with your strap-on harness, you need to ensure you choose a dildo with a flanged base, suction cup, or moulded balls. Without one of these, you will find that your dildo will fall straight through your o-ring, not to mention that sex toys without a flared base can be a health hazard for anal play! Dildos with moulded balls or extra length may be less upright than you would hope once in your harness, so a second optional o-ring can be added to your harness set-up to secure it.
