Types of Strap-Ons and Harnesses
Traditional O-ring harness and separate dildo
The most flexible configuration — a harness worn around the hips and thighs with an O-ring or similar attachment point that holds a compatible dildo in place. The dildo is removable, meaning the harness can be fitted with different dildos of different sizes, shapes, or materials depending on the session. This is the most customisable approach and the one most experienced strap-on users gravitate toward, but it requires buying a compatible harness and dildo separately (or as a matched set) and spending slightly more time finding the right combination.
All-in-one strap-on sets
A harness and attached dildo sold as a matched unit — the most accessible entry point because the compatibility and sizing are pre-sorted. Sets like the Ingen Easy Strap-On and the Size Matters Silicone Dildo Strap-On are complete first-purchase solutions that remove the guesswork of matching a harness and dildo independently. Ideal for first-time buyers who don't yet have preferences about specific dildo sizes or configurations.
Strapless strap-ons
A design that eliminates the harness entirely — the penetrating partner inserts a bulbed end into their vagina, which holds the toy in place via internal grip, allowing penetration of the receiving partner from the other end. These require stronger pelvic floor muscles and more experience to use effectively than harness-based designs; they're not recommended as a first strap-on for most couples.
Thigh harnesses
A harness that straps to the thigh rather than the hips, holding a dildo at thigh level for penetration from a different angle. Popular for couples where the penetrating partner has a disability affecting hip mobility, or for couples who want to experiment with different penetration positions and angles.
Hollow strap-ons
A strap-on with a hollow internal cavity, designed for a male partner to wear over their penis. These add length and girth beyond the wearer's natural anatomy, or can be used when the wearer has erectile difficulty. The Size Matters Hollow Strap-On is this design — a practical option for couples who want the benefits of a strap-on alongside the sensation of the male partner's natural anatomy.
Choosing the Right Dildo for Your Harness
Size for first-time receiving partners
Smaller than instinct suggests. For anal receiving partners in particular, anything over 3–4cm in diameter is too much for a genuine first attempt — start slim and work up across sessions. For vaginal use, first-time receiving partners with harnesses typically find a moderate length (15–18cm insertable) and comfortable girth more satisfying than a dramatic size jump from the wearer's natural anatomy.
Firmness
Silicone dildos range from very soft and flexible to quite firm. A moderately firm silicone dildo is easier to use with a harness than an extremely soft one, which can make insertion difficult. A dual-density silicone (firm core, softer exterior) represents a good balance for most first-time use.
Harness compatibility
O-ring harnesses hold dildos by the base, so the dildo needs a flared base to be held securely in the ring. Most purpose-made strap-on dildos are designed with this in mind; confirm the base diameter is compatible with your harness ring before buying separately. Browse our full dildos and dongs range for harness-compatible options.
Vibrating vs non-vibrating
A vibrating dildo in a harness transmits some vibration to the penetrating partner through the harness as well as to the receiving partner during penetration. Many couples find this meaningfully improves the experience for the penetrating partner, who otherwise doesn't feel direct stimulation in the same way a receiving partner does. The Secret Kisses Rosegasm Harness Set includes multiple dildo options including vibrating versions for exactly this reason.
Getting the Fit Right
Harness sizing
A harness that's too loose allows movement during thrusting that reduces control and can cause chafing. One that's too tight is uncomfortable and restrictive. Most adjustable harnesses accommodate a wide range of hip sizes through strap adjustment; measure hip circumference before buying and check the manufacturer's sizing chart.
O-ring size and dildo base
The dildo's base needs to be larger than the O-ring to be held securely, but not so much larger that insertion through the ring during setup is difficult. A base around 5–6cm in diameter against a standard 4.5cm O-ring is a typical good fit.
Dildo positioning
The dildo should sit naturally at an angle that points outward from the body rather than straight up or down when the harness is worn and the wearer stands upright. Test the angle before use and adjust straps if needed. A slight upward angle is usually preferable to a downward one for most penetrative positions.
Preparation for First Use
Practise alone first
Putting on a harness and moving around in it alone before a partnered session removes any awkward learning curve mid-intimacy. Find out how the straps adjust, how the dildo positions, and how thrusting movement feels before a partner is involved. This takes 10 minutes and significantly improves the quality of the first partnered experience.
Lubrication is essential
Generous water-based lubricant on both the dildo and the receiving partner's opening, reapplied during the session as needed. This is non-negotiable for anal use and strongly recommended for vaginal use regardless. The difference between adequate and inadequate lubrication in strap-on use is the difference between a comfortable, pleasurable experience and an uncomfortable one.
Start with arousal and foreplay
Particularly for anal receiving partners, arousal before any penetration begins matters enormously. An aroused, relaxed body accepts penetration more comfortably than one that isn't. Spend real time on foreplay before introducing the strap-on.
How to Use a Strap-On — Step by Step
Step 1 — Fit the harness and check the angle
Put on the harness, adjust straps to comfortable but secure tightness, and check the dildo's resting angle. Apply lubricant to the dildo generously before any contact with the receiving partner.
Step 2 — Warm up the receiving partner thoroughly
Manual stimulation, oral sex, or a smaller toy before the strap-on is introduced. The receiving partner's readiness matters more than anything else for a positive first experience.
Step 3 — Begin with the tip only
Start with just the tip of the dildo at the opening, apply gentle consistent pressure, and allow the receiving partner to accept it at their own pace. Never push past resistance. For anal use especially, the first centimetre of insertion is the most significant — once past the sphincter, subsequent depth is more comfortable.
Step 4 — Communicate continuously
The penetrating partner can't feel what the receiving partner is experiencing through the strap-on the way they would with natural anatomy. Verbal communication — feedback about pace, depth, angle — is the only way the penetrating partner knows what's working. Make this part of the session rather than an interruption to it.
Step 5 — Establish a rhythm that suits both partners
A slower, shallower rhythm to start, building gradually based on the receiving partner's response. The penetrating partner has more physical control in a strap-on session than feels intuitive at first — controlled, deliberate movement is more effective than rushing.
Step 6 — Reapply lubricant as needed
Particularly for longer sessions or anal use — water-based lubricant dries out with extended use and should be refreshed rather than ignored when friction increases.

Best Positions for Strap-On Use
Doggy style — most control for the penetrating partner
The most commonly recommended first position for strap-on use, particularly for pegging (anal). The penetrating partner has excellent visual control over depth and angle, and the receiving partner can adjust their position independently. Start with shallow, slow movement and build from the receiving partner's verbal cues.
Missionary — face-to-face connection
A more intimate first position for couples who want to maintain eye contact and verbal communication throughout. The angle can be adjusted by placing a pillow under the receiving partner's hips to change the penetration angle.
Receiving partner on top
Gives the receiving partner complete control over depth, angle, and pace — often the most comfortable option for first-time anal receiving partners since they can lower themselves at their own speed without depending on the penetrating partner's control of movement.
Cleaning and Care
Dildos
Silicone dildos: warm water and dedicated toy cleaner after every use. Non-motorised silicone can be boiled for full sterilisation between partners. Never use silicone-based lube with silicone dildos.
Harnesses
Most fabric harnesses are machine washable on a gentle cycle. Leather harnesses require a damp cloth wipe and conditioning. Check the manufacturer's care instructions for your specific harness. Remove the dildo ring before washing.
Between partners
Sterilise the dildo fully between partners, or use a new condom on the dildo for each partner. Don't transfer a dildo between anal and vaginal use without sterilising or changing the condom.
Frequently Asked Questions — Sydney
Can men wear strap-ons?
Yes. Hollow strap-ons are specifically designed for male wearers — the penis fits inside the hollow shaft, adding length and girth while the harness holds everything in place. This is used for adding size, for managing erectile difficulty, or simply as a different sexual experience. The Size Matters Hollow Strap-On is designed exactly for this purpose.
What's the difference between a strap-on for pegging and one for same-sex couples?
Primarily the dildo choice and size considerations. For pegging (anal receiving), a slimmer, shorter dildo with a gentle curve is appropriate for beginners. For same-sex female couples using a strap-on for vaginal penetration, preferences vary more widely and tend to more closely mirror personal size preferences for vaginal toys. The harness itself is the same in both cases.
How do I know which size dildo to start with?
For anal receiving partners: 3cm diameter maximum and under 15cm insertable length for a genuine first attempt. For vaginal receiving partners: guided by existing experience with internal toys — start at or below the size you're already comfortable with, then size up as desired. Browse our full dildos and dongs range for all sizes.
Does the penetrating partner feel anything during strap-on use?
With a standard harness and separate dildo, the penetrating partner feels the physical movement of thrusting but doesn't receive direct genital stimulation through the toy. The psychological and emotional experience is often described as more stimulating than expected regardless. A hollow strap-on adds direct penile stimulation for male wearers.
Is a strap-on safe for anal use?
Yes, with appropriate preparation — adequate lubrication, starting small, going slowly, and maintaining communication throughout. See our pegging preparation guide for detailed anal-specific technique.
How do I clean a silicone dildo properly?
Warm water and dedicated toy cleaner after every use. For full sterilisation between partners — boiling in water for 3 minutes, or running through a dishwasher without soap. Non-porous silicone sterilises fully, unlike porous materials.
What lubricant is safe with silicone dildos?
Water-based lubricant only. Silicone-based lubricants degrade silicone toy surfaces over time. Browse the Sex Toys Sydney lubricants range for compatible options.
