Good to know

Strap-Ons & Harnesses — your questions, answered

choosingHow do I choose a strap-on or harness?
Start with fit and O-ring size — the harness has to sit securely on the wearer and hold the dildo you want to use. Decide between a ready-to-wear strap-on set or a separate harness you pair yourself. The Coyscore weights secure fit, comfort and body-safe materials, so a strong score flags the dependable options.
comparisonStrap-on set vs. harness-only — which should I buy?
A strap-on set includes a harness and a matched dildo ready to go, ideal if you want one simple purchase. A harness-only lets you choose and swap your own O-ring-compatible dildos over time, which is more flexible and often better quality. Beginners often prefer a set; those with a favourite dildo prefer harness-only.
safetyAre the materials body-safe, and how do I check the dildo fits?
Yes — harnesses use body-safe straps and hardware, and any paired dildo tagged Body-safe is non-porous, medical-grade silicone checked against the manufacturer sheet. To fit, match the dildo's base diameter to the harness O-ring size, and make sure it has a flared base so it stays secure. Use water-based lube throughout.
beginnersAre strap-ons good for beginners and first-time pegging?
Yes — a ready-to-wear set with an adjustable harness and a slimmer dildo is the easiest way to start. Take it slowly, use plenty of water-based lube, and communicate throughout, since the wearer can't feel depth the way the receiver does. Adjust the straps for a snug, comfortable fit before you begin.
careHow do I clean and care for a strap-on and harness?
Wash the dildo with warm water and a toy cleaner before and after use, then air-dry fully. Clean the harness per its material — wipe leather-look straps, and hand-wash fabric harnesses, letting them dry completely before storing. Keep the O-ring and buckles free of lube build-up, and use water-based lube throughout.
deliveryIs delivery discreet, and can I return a harness?
Always — everything ships in plain, unbranded packaging with a discreet billing descriptor, and NZ orders over $60 ship free. Harnesses and apparel that are unworn and unopened may be returned, but for hygiene reasons opened intimate items can't be. We'll always make a genuine fault right, and tracking is emailed.

Buying guide

How to choose a strap-on and harness

A great strap-on is really two decisions — the harness that fits, and the dildo that pairs with it. Here's what the Coyscore weighs, and how to match them.

Coy buying-guide card — “Fit and comfort come first”

1. Fit and comfort come first

A strap-on only works if the harness fits the wearer securely and comfortably. Look for wide, adjustable straps and a design that suits your body and preferred style, whether that's a classic thigh-and-waist harness or briefs-style. A snug, stable fit means better control and less fuss mid-play.

  • Choose wide, fully adjustable straps for a secure fit
  • Briefs-style suits comfort; strap-style suits adjustability
  • The Coyscore weights secure fit and comfort from reviews

2. O-ring and dildo compatibility

The O-ring size decides which dildos fit. Match the ring to the base diameter of the dildo you want, and always use a dildo with a flared base so it stays put. Many suction-cup and classic styles are harness-compatible, so you can build a set that suits you.

  • Match O-ring size to the dildo's base diameter
  • Only use dildos with a flared, harness-safe base
  • Interchangeable rings add flexibility over time

3. Body-safe materials and getting started

Pair a body-safe, non-porous silicone dildo with a comfortable harness, go slowly, and communicate — the wearer can't gauge depth the way the receiver can. Use plenty of water-based lube and adjust the straps before you begin. The Coyscore combines fit, comfort and material into one clear rating.

  • Body-safe silicone dildo plus an adjustable harness
  • Go slow, communicate, and lube generously
  • The Coyscore ring rates each pick at a glance
