Double-Ended Dildos — Buying Guide
A double ended dildo gives you two insertable ends on one flexible shaft — solo users get a built-in handle, couples share penetration simultaneously, and anyone exploring double penetration has a tool actually built for it. If you prefer single-ended options, our realistic dildos or curved G-spot dildos offer precision for solo use. All Sustory double dildos are platinum-cured silicone — fully body-safe for both partners.
How to Choose the Right Double Dildo
Length — Insertable Per End, Not Total
For partner use, 5"–7" insertable per end with 12"–18" total is the functional range. For solo use, 10"–14" total is easier to manage. We list insertable length per end on every product — not vague total measurements.
Flexibility & Diameter
Partner use needs a shaft that bends 90°+. Look for Shore A under 25° outer hardness. Some double dildos have symmetrical ends; others are differentiated — one end narrower, one wider. Check both end diameters independently. Users who prefer significant girth may also want to explore our thick dildos.
Size Reference Table
| Use Case | Total Length | Insertable Per End | Diameter |
|---|---|---|---|
| Partner shared | 14"–18" | 5"–7" | 1.2"–1.6" |
| Solo — one end active | 10"–14" | 6"–8" | 1.4"–1.8" |
| Solo double penetration | 12"–15" | 4"–6" | 1.0"–1.4" |
How to Use & Care
Partner Use
Each partner inserts their end to comfortable depth. Agree on pace before starting — your movement directly affects your partner's sensation. For hands-free partner configurations, a suction cup dildo may better suit your setup.
Solo Use & Anal Safety
Hold the uninserted end as a handle for better leverage. For anal use, the connecting shaft acts as a retention feature when used correctly — never insert beyond the midpoint. New to anal play? Start with our anal dildos or tapered dildos before moving to double-ended designs.
Lube & Cleaning
Water-based lube only. Apply to both ends before use, reapply as needed. Wash with warm water and mild soap after every session. Fully sterilizable.
Frequently Asked Questions
Can one person use a double-ended dildo alone?
Yes — one end inserts while the other serves as a handle. Solo double penetration is also possible but requires positioning practice across separate sessions first.
What length works for two partners?
14"–18" total, with 5"–7" insertable per end, fits most partner configurations.
Are double dildos safe for anal use?
Yes, when used correctly — the shaft length prevents full insertion and acts as a natural retention feature. Never exceed the midpoint anally.
What material is safest when sharing a toy?
Medical-grade platinum silicone only — non-porous, fully sterilizable, and free from phthalates. All Sustory products pass SGS third-party testing.
