Types of Dildo Bases ⁠— and 6 things you could do with them

Play with positions beyond missionary and hand-thrusting a dildo.

The non-insertable portion of a dildo make a considerable difference.

I’ve previously written about making masturbation feel more realistic, which encompassed a wide range of toys and tricks — from Fleshlight mounts to VR porn. Think of this dildo base guide as a companion piece to that article.

Flat base dildos vs. suction cup bases

If your dildo already comes with a suction base, rejoice! If it doesn’t, don’t think of dildos with flat bases as merely lacking features — they’re versatile because you can attach so many add-ons to them.

Double-sided suction cup adapter

Expand your dildo selection beyond those with built-in suction cups

You can convert a flat-based dildo into a suction cup dildo with a double-sided suction cup — get one from Lust Arts or Uberrime.

Attach one end of a double-sided suction cup to a dildo base and the other to a smooth, clean surface. Try a mirror or floor tile. (Or wrap the Body Dock Lap Strap thigh harness around a pillow, chair seat, or full backpack!)

Double-sided suction cups come in a wide range of sizes. That’s a big deal if you’re attaching a huge and heavy dildo to the wall.

As well, some glass dildos come with detachable silicone suction cups. Ride on!

Add a silicone cushion or grinder to the base

Squishy humping toys can be fun alone, but you can also attach some of them to flat dildo bases for added stimulation during harness play!

While you’re penetrating a partner with a strap-on, your vulva has something to grind up against (or provide soft cushioning).

There’s a range of grinders made by indie silicone artisans like Vixen Creations and Bananapants. Some stick to flat dildo bases, while others wrap around them or are held in place by a harness.

Harnessing or mounting dildos

Flat base dildos can be easy to harness and mount under a few conditions:

• The base is laterally flared but not too thick
• The phallic part of the dildo can adequately fit inside an O-ring

Dildos with suction cup bases also tend to be harnessable. For mounting certain suction cups and flat base dildos while solo, try putting a thigh harness over a pillow — the Body Dock Lap Strap has a roomy docking plate for a wide range of suction cup dildo bases (or adapters!)

I like also the Liberator Wing a lot. It has slots for both cowgirl/cowboy/cowpoke and doggy-style positions. There’s a size limit, though. The following specs are ideal for fitting through the Liberator Wing’s holes:

• Dildo diameter under 2”
• Base diameter under 3”
• OR, if the base is bigger, a somewhat flexible one that folds down easily
  • Dildo bases with broad, rigid balls probably wouldn’t be the best fit

Why do some dildos have holes in the base?

Bullet holes, Vac-U Lock, and suction dildos

Some dildos have holes in the bases with varying sizes and functions. Some are great for slipping bullet vibrators inside, while others are better for even more ways to mount!

0.8” wide bullet cavity base dildos

Best for standard size bullets but seldom suction cup adapters

The most versatile bullet vibrators have hard plastic shells in the 0.75” to 0.85” diameter range. They transfer vibrations well and fit inside a wide array of vibrating dildos, from the well-known Tantus and Vixen Creations to smaller companies like Cute Little Fuckers.

Sex toy reviewers tend to call the We-Vibe Tango X and BMS Swan Maximum the gold standard — it’s unbeatably rumbly, though the Swan Maximum is more powerful.

If you want a suction cup adapter for a dildo bullet hole of this size, try the silicone one made by Tantus.

Dildos with 0.9” to 1″ wide Vac-U-Lock holes

Fits a limited range of bullets, but you get way more mounting options

Vac-U-Lock fucking machines

Many fucking machines come with Vac-U-Lock style dongles, including the full-on Kink Power Banger. For a more compact sex machine, the miniature Velvet Thruster Universal connects to dildos with lock-on holes, though the stroke length is relatively short at 1.5”.

Bullets for Vac-U-Lock Holes

My main recommendation for a bullet to put in Vac-U-Lock ports is the Blush Limited Addiction.

If you want the most massive vibrating dildo combination I’ve ever tried, put the Limited Addiction inside the Hankey’s Toys Topher Michels. You’re welcome.

Finally, there’s a suction cup adapter for this size Lock-On hole, too. Or try a Vac-U-Lock/Lock-On harness.

Double-ended dildos

The perk of double-ended dildos: more options for penetration sensation in one toy! njoy’s Eleven and Le Wand’s Contour, for example, have one big end and one small end.

However, the downside is that your positioning options aren’t as plentiful. Still, the Liberator Wing’s dense foam slots can hold dildos without bases! This way of mounting toys is best for hard material dildos like the Le Wand Arch, njoy Eleven, and Desirables Dalia.

Velvet Thruster Prime screw ports and attachments

Last but not least: the new Velvet Prime models have accessibility and positioning accessory options!

The tweaks I mentioned above can apply to the Velvet Thrusters too:

• Screw in a suction cup
• A long reach handle for partner play
• An angled handle for solo times
• Harness or mount it!

You can also swap the Velvet Thruster Prime head out for a different dildo attachment. Or put a Vac-U-Lock dildo on the Thruster Universal. And harness that.

Hell, yeah. The future is now.
