Penis Extensions & Sleeves: your questions, answered

choosingHow do I choose a penis extension or sleeve?
Match the fit to your size first — a sleeve should sit snugly without slipping — then decide how much length, girth or texture you want. Softer body-safe silicone feels the most natural. The Coyscore weights secure fit, material safety and feel from real reviews, so you can find the right style quickly.
comparisonExtension vs. sleeve vs. hollow strap-on — what's the difference?
An extension adds length beyond your own; a girth sleeve slips over to add width and texture; a hollow strap-on supports partnered play when firmness is a concern. Beginners usually start with a stretchy, close-fitting silicone sleeve before trying longer extensions or supportive styles.
beginnersWhich extension or sleeve is best for beginners?
A soft, stretchy silicone sleeve with modest added girth is the easiest first choice — it flexes to fit and feels natural. Look for the beginner-friendly tag, start with plenty of water-based lube, and talk with your partner about comfort. You can explore longer extensions once you know what suits you both.
safetyAre extensions and sleeves body-safe?
Everything tagged Body-safe is non-porous silicone verified against the manufacturer sheet; porous TPE or jelly is flagged, never quietly left off. Use a water-based lube — silicone lube degrades silicone — and stop if anything pinches or feels uncomfortable. Clean thoroughly before and after every use to keep it hygienic.
careHow do I clean and store a sleeve or extension?
Wash with warm water and toy cleaner before and after use, turning textured sleeves inside out to rinse fully, then air-dry completely. Store silicone pieces separately from other toys and away from dust. A light dusting of renewing powder keeps soft materials from getting tacky between uses.
deliveryIs delivery discreet, and can I return it?
Always — every order ships in plain, unbranded packaging with a discreet billing descriptor, so nothing gives it away. We ship NZ-wide with free shipping over $150. We don't offer change-of-mind returns or exchanges, whether or not it's been opened, but we'll always put a fault right.

How to choose an extension or sleeve

Fit and material decide whether a sleeve feels natural or gets left in the drawer. Here's what the Coyscore weighs — and what to look for yourself.

Coy buying-guide card — “Get the fit right”

1. Get the fit right

A sleeve or extension should sit snugly without slipping or pinching — fit matters more than added size. Stretchy silicone flexes to fit most people, which is why it's the recommended starting point over rigid or oversized styles.

  • Snug without slipping is the fit test
  • Stretchy silicone forgives sizing
  • Start modest, then explore more length or girth

2. Body-safe material and feel

Only non-porous silicone is genuinely body-safe and gives the most natural feel; porous TPE or jelly can trap bacteria, so we flag anything unverified rather than hide it. Pair with a water-based lube to protect silicone and keep everything comfortable.

  • Non-porous silicone is the body-safe choice
  • We flag any unverified material on the card
  • Use water-based lube — silicone lube degrades silicone

3. Length, texture and the Coyscore

Once fit and material are sorted, added length, girth and texture come down to what you and a partner enjoy. Reviewers focus on secure fit and natural feel, so the Coyscore weights those directly — drawn from thousands of real reviews across the web, not our own stars.

  • The Coyscore weights secure fit and feel
  • It aggregates real cross-web reviews, not Coy reviews
  • Beginner-friendly picks are tagged
