Key Features:

The graduated design features a 1.8 inch tip expanding to a 2.5 inch middle knot for intense anal stretching sensations. Premium platinum cured silicone construction ensures body safe penetration during extended play sessions.

Ribbed texture along the upper shaft creates enhanced friction against anal walls during thrusting movements. The prominent middle knot acts as an internal plug delivering intense pressure and fullness for advanced users.

Eight inch total length provides deep anal penetration while the 2.8 inch flared base ensures safe use and prevents full insertion. Harness compatible design enables partnered pegging and strap on play scenarios.

Waterproof silicone construction allows for anal play in shower or bath environments. Non porous material resists bacteria buildup and cleans easily with soap and water for hygienic repeated use sessions.

Substantial 15 ounce weight delivers satisfying heft during anal thrusting movements. The knot creates electrifying sensations during insertion and removal while the flared base provides secure grip control during masturbation.

What it does

The Fido-1 works by delivering graduated sensation as you take it deeper. You start with a manageable 1.8-inch tip that introduces you gently, then progress into a ribbed section that stimulates your most sensitive anal tissue. At the heart of the design is a 2.5-inch knot that acts like an internal plug, creating a feeling of fullness and pressure that intensifies with each movement.

What makes this dildo stand out is the sensation of the knot passing through during insertion and withdrawal—that moment of stretch and release is electric. Glass Prostate Toys offer a different rigidity and temperature play, but the Fido-1's silicone flex and textured surface create a more forgiving, multi-sensory experience that builds pleasure over time.

Size and first use

Start with the Fido-1's 1.8-inch tip—it's designed to introduce you gently to what's coming. Use plenty of lubricant and go slowly; there's no rush to take the full knot immediately. Most people find it takes several sessions to work up to the widest point comfortably. Cockringshop specialises in products for men and couples at every experience level, so don't hesitate to take your time. The weight of the sex toy means you'll feel every movement, which helps you tune in to what your body is ready for next.

How to use it

Position yourself on your back, side, or on all fours—whatever lets you control depth easily. Apply lubricant generously to the dildo and your opening, then guide the tip in slowly. Breathe deeply and relax your muscles as you press forward, pausing if you feel resistance. Once the knot passes through, you'll feel a satisfying sensation of fullness.

Movement can be slow and deliberate or faster and more vigorous—the flared base gives you a secure grip either way. When you're done, rinse thoroughly with warm water and mild soap, or use a toy cleaner. Store it in a cool, dry place away from direct heat or sunlight to keep the silicone in top condition.

Feature breakdown

Feature Specification Benefit Experience
Graduated diameter 1.8" tip to 2.5" knot Builds sensation gradually Comfortable start, intense finish
Ribbed upper shaft Textured surface Heightens stimulation Waves of pleasure as you move
Prominent middle knot 2.5" diameter bulge Acts as internal plug Powerful stretch and fullness
Flared base 2.8" wide anchor Safe, stable, harness-ready Control and partnered flexibility

Who it suits

The Fido-1 is ideal for anyone who has some anal experience and wants to feel a more substantial stretch and fullness. The graduated design appeals to people who enjoy building sensation over time rather than jumping straight into maximum width. Solo players love the weight and control; couples enjoy the harness compatibility for pegging and strap-on play. It's a serious tool for serious exploration.

Skip this one if you're brand new to anal play—the knot is substantial and requires a relaxed, experienced body. If you prefer smaller or firmer sex toys, or if you want something you can use hands-free without a harness, look elsewhere. This dildo demands your attention and engagement, which is exactly what some people want but not what everyone needs.

Tested and quality-checked

Every new line we stock is inspected by hand before it goes live — we check the build, the finish, and the materials, and we confirm it is safe and fit for how it will be used. Nothing is used for its intended purpose; it is examined, checked, and re-boxed. What that means for you is simple: you receive a piece we have already vetted, not a guess off a supplier's pallet.

How it compares

Prostate Dildos focus on internal massage of the prostate gland itself, with curves and angles designed for that specific target. Anal dildos like the Fido-1 prioritise depth, stretch, and internal sensation across the whole anal canal without needing to angle for a particular spot. The Fido-1's knot and ribbed texture create pleasure through fullness and texture rather than precision prostate contact—a different approach that many people find more immediately satisfying.

Please read — safety first. Keep all stimulation below the waist and never route current across the chest or through the heart; avoid use entirely with a heart condition, a pacemaker, or in pregnancy. Never share between partners without cleaning the item first or using a fresh condom. This information is general in nature only and is not medical or professional advice, and does not take your personal circumstances into account. Stop use and speak with a qualified medical professional if you have a relevant health condition, take medication for erectile function or blood pressure, or notice pain, numbness, or discolouration that does not settle.

What you can use it with

Pair the Fido-1 with Couples Intimacy Kits for partnered play that includes harnesses, positioning aids, and other tools designed to work together during shared sessions. A harness lets your partner control depth and rhythm while your hands are free to explore elsewhere, or to grip and steady yourself. This combination transforms solo anal play into a fully partnered experience where both people stay engaged and in control.
