Dildo Shapes Guide Australia - Curved, Spiral, Ridged & Unique Shaped Dildos

Dildo shapes are realistic, double-ended, strap-on, suction cup, inflatable, vibrating, and hollow designs made from body-safe silicone or TPE. Each shape delivers different sensations and suits different play styles, if you're going solo or with a partner.

About Dildo Shapes

Dildo shapes are penetrative sex toys designed in specific forms to suit different bodies, preferences, and play scenarios. The main types include realistic dildos with textured, lifelike details; double-ended designs for simultaneous penetration or shared use; strap-on harness sex toys for partnered play; suction cup bases for hands-free mounting; inflatables for adjustable girth; vibrating models for added stimulation; and hollow extensions for wearable play. Most are made from medical-grade silicone, TPE, or latex—materials that are non-porous, easy to clean, and safe against skin.

These sex toys work for beginners exploring realistic designs, couples wanting shared sensations, and experienced players seeking specialized shapes. If you're interested in extending length or girth during partnered sex, Penis Extenders offer a complementary option. Dildo shapes cater to all bodies and experience levels, making them a reliable choice for safe, body-matched play.

What makes Dildo Shapes different

Unlike single-purpose vibrators, dildo shapes are defined by their physical form rather than their power. Each shape targets different sensations: realistic dildos mimic anatomy for authentic feel, double-ended sex toys enable mutual penetration, and suction cups free your hands entirely. Strap-on harness designs let partners take an active role in penetration, while inflatable and hollow options add adjustability or extension potential. If you and a partner enjoy hands-free or remote-controlled play, Remote Control Couples Toys can complement dildo-based sessions.

Types of Dildo Shapes

Realistic dildos. These feature textured, veined, or anatomically detailed surfaces that mimic natural anatomy. They're ideal if you want a lifelike feel and familiar shape for vaginal or anal penetration.

Double-ended dildos. Both ends are insertable, so two people can use one dildo simultaneously or one person can enjoy simultaneous vaginal and anal penetration. They range up to 400 mm in length, offering flexibility for different body types and preferences.

Strap-on harnesses. These dildos attach to a harness worn by one partner, allowing hands-free thrusting and deeper control during partnered sex. Wearable Couples Toys include strap-on systems designed for comfort and secure fit during extended play sessions.

Suction cup dildos. A suction cup base adheres to smooth surfaces—shower tiles, glass, or furniture—so you can ride hands-free or angle for solo play. They're popular for solo exploration and require no hands or partner involvement.

Inflatable dildos. These expand to your preferred girth using a hand pump, letting you start smaller and adjust as you relax. They suit people exploring anal play or those who want customizable stretch.

Vibrating dildos. Internal or external vibration adds buzz to realistic, double-ended, or strap-on shapes for extra stimulation during penetration.

Hollow dildos. These slip over an existing penis or strap-on to extend length or girth without replacing your main sex toy. They're often used for added sensation or to reach deeper during partnered play.

How they compare

How to choose a dildo shape

Start by thinking about what you want: realistic texture, partnered play, hands-free use, or adjustable size. If you're new to penetration, a smaller realistic dildo (under 180 mm) or an inflatable lets you go at your own pace. For couples, double-ended or strap-on designs add shared control and mutual sensation. If you want hands-free play, suction cups are reliable on shower walls and smooth furniture. For anal play, always choose a flared base to prevent the dildo sliding inside, and consider starting with a smaller width—most people find 30–40 mm comfortable to begin.

Material matters: silicone is the safest, most durable choice and works with water-based or hybrid lubricants. If you're preparing for anal penetration, Enemas and Douches help you feel confident and clean before play. Match the size to your body—longer isn't always better, and wider isn't right for everyone. Read customer reviews to see how others found the fit, and don't rush into the largest size just because it's available.

After years of helping customers choose dildo shapes, we've learned that size anxiety is real—and unnecessary. Most people start too large. A realistic dildo around 150–180 mm and 35–40 mm wide is genuinely satisfying for most first-timers, whether vaginal or anal. Going smaller first teaches you what you actually enjoy, and you can always explore larger shapes later. There's no prize for jumping straight to the biggest option.

Suction cup dildos are brilliant, but they only work on truly smooth, non-porous surfaces. Shower tiles work; textured bathroom walls don't. Test the suction before you rely on it during play—a weak seal is frustrating mid-session. If you're using one for partnered play, make sure both of you are comfortable with the angle and depth before things get intense.

Double-ended dildos are fantastic for couples, but they require communication about depth and pace. The flexible midsection means one partner might feel more sensation than the other depending on angle. Start slowly, check in often, and don't assume the same rhythm works for both bodies. If you're exploring this shape solo, remember you're in full control—take your time and listen to what feels right.

Care and cleaning

Wash your dildo with warm water and antibacterial soap or a dedicated toy cleaner after every use. Silicone and TPE are non-porous, so they don't trap bacteria like porous materials do—but regular cleaning keeps them fresh and hygienic. Dry thoroughly with a lint-free cloth and store in a cool, dry place away from direct sunlight. Never store silicone dildos in contact with other silicone toys, as they can degrade each other over time.
