Double-ended dildos

Also called · double dildo · double-sided dildo
At a glance
In one line
A single dildo with an insertable end at each side, so both partners are penetrated by the same toy.
Usually looks like
Either a long straight shaft used facing each other, or a curved model whose short end anchors inside the driving partner.
Gear needed
Yes: the toy, generous lube, and often a harness to stop the anchored end sliding out.
Talk about first
Who controls the thrusting, whether a harness is used, and how you switch when the position fails.

A double-ended dildo is a single shaft with an insertable end at each end, designed so two partners can be penetrated at the same time, or so one end can sit in a harness while the other stays inside the wearer. Lengths, thicknesses, and flexibility vary widely, and some are U-shaped or have a rigid center section rather than bending along their whole length.

Simultaneity is the whole appeal and also the main problem: keeping both ends seated while either partner moves is harder than it looks, very flexible models fold instead of transmitting movement, and stiff ones restrict which positions work at all. Most couples settle on one partner doing the moving, or use the toy in a harness so that only one end has to stay put.

This is another item that tends to get downgraded after a first attempt, and a middling score often means the idea appeals but the mechanics disappointed. High scores come from people who want the mutual version of penetration rather than taking turns with one toy. Low scores are usually about logistics rather than about penetration itself.

What a score means here Double-ended dildos
  1. 0 Hard no: sharing one toy between both bodies at once is not something you want.
  2. 1–33 1-33: a novelty you have tried or would try once, and it does not hold up.
  3. 34–66 34-66: fun for a stretch, usually the harness version where one partner drives.
  4. 67–99 67-99: a regular part of what you do, with a specific model you know works.
  5. 100 100: simultaneous penetration from one shared toy is the thing you are actually after.
Rating it

A low score means the shared-toy arrangement is not worth the coordination it takes; a high score means being penetrated at the same time as a partner is something you specifically want rather than a novelty.

Common misconceptions
Worth knowing

Body-safe silicone is worth the money here, since porous TPE and PVC cannot be fully cleaned. A shared shaft carries fluids directly between partners and cannot be usefully covered by a single condom, so wash it thoroughly and treat it as shared rather than personal equipment.

About this item Frequently asked

Double-ended dildos — questions people ask

what is a double-ended dildo and how do you use one
A double-ended dildo is one toy with an insertable end at each side, so both partners can be penetrated at once. Two designs exist and they behave very differently. The long straight kind is used facing each other or in a scissor-style position, with both partners pushing toward the middle. The curved kind has a short bulb that anchors inside one partner, usually held in a harness, so that partner can thrust with the longer end. The curved harness version is far more usable in practice.
how do you keep a double dildo from slipping out
Use a harness, or accept that one partner has to hold it. The straight double-ender has nothing to grip, so any thrusting pushes it out of one end or the other, and pelvic floor tension alone will not hold it through a full session. Harness-compatible curved models solve this by fixing the anchoring end in place, which turns it into a strap-on that also penetrates the wearer. Failing that, one partner holding the shaft mid-length gives control and stops the depth drifting. Extra lube makes slipping worse, so apply it to the ends rather than the middle.
double-ended dildo vs strap-on, which is better for penetrating a partner
A strap-on is more reliable for penetrating; a double-ender is for wanting penetration on both sides at once. Wearing a strap-on gives stable control of depth, angle and pace, and the wearer's own sensation comes from the harness base or an added vibrator. A double-ender trades some of that stability for internal sensation in the driving partner. Many pairs end up with a harness-compatible double-ender as a compromise, which is effectively a strap-on that penetrates the wearer too.
what score makes sense for double-ended dildos
Score how much you want simultaneous shared penetration, not how the one attempt with a cheap toy went. A 0 marks it as a hard no. On the 1 to 100 scale, a novelty you would repeat sits low, wanting it as an occasional variation sits mid, and wanting it as a standing part of your sex sits high. Since a lot of low scores here come from the toy sliding out rather than the idea itself, it is worth separating dislike of the act from dislike of the equipment before you set the number.
what material should a double dildo be and how do you clean it
Buy 100% silicone and avoid TPE, PVC and jelly, which are porous, hold bacteria in the surface, and cannot be sanitised however hard you scrub. Use water-based lube, since silicone lube degrades silicone toys and leaves the surface sticky. Wash with soap and warm water after use, dry it fully, and boil pure silicone for a few minutes if you want it sterilised. Store silicone toys apart from each other, because some formulations react on contact and go tacky. Since a double-ender is inside two people at once, regular STI testing matters more here than the cleaning routine does.
