Dual-Density Dildo Guide – 100% Safe Silicone

Soft skin, hard inside. The best dual-density dildos are a brilliant combo, made to (1) create a more lifelike faux-penis, and (2) be more comfortable inside you.

What’s the big deal: What is a dual-density dildo? Also called “dual-layer,” it combines two different firmnesses into one product. That’s: fleshy-softness, plus solid within so it’s not floppy.

For 8 years, I’ve collected dual-density silicone, since cheaper “TPE” (thermoplastic elastomer) dildos are prone to degradation and mold growth. In contrast, platinum silicone is functionally nonporous, repelling bacteria, viruses, and yeast and mold. And, it’s best to buy from a reputable body-safe toy seller—who sources their dildos from known manufacturers—vs. buying from random Amazon sellers who are not legally bound to tell the truth about sex toy materials. So: which are the best dual-layer dildos right now?

Best-Of Dual-Density, Summary

Best dual-density dildos

Skip to the specific review, below, for more details on why each dildo stands out; plus more dual-density options that are safe silicone, including King Cock Elite, Shaft dildos, Tantus realistic dildos, and RealCock2.

Dual-Density Dildo Pros & Con

Dual silicone dildos were made to feel more realistic. But, if you’re not looking for a phallic shape, they can also meet the need for softer comfort. Dual-density silicone pluses and minuses:

Pros

  • Comfortable plus body-safe (if you choose silicone).
  • Soft outside + firm core: Imitates an erection better.
  • All about the lifelike feel:
  • But, also better (in non-realistic shapes too!) for anal sex or anyone who likes gentle penetration.
  • Little to no odor.
  • Safe for many years of use.
  • Can be sanitized to kill bacteria, yeast, and other germs instantly.

Cons

  • Sometimes rubbery or sticky-feeling. (Varies by brand.) Be sure to use lubricant!
  • Not ultra-slick. Some dildo-receivers prefer glass, metal, or gloss-finish silicone dildos.
  • Super-soft exterior isn’t the firm pressure some people need for G-spotting or prostate.

Even though dual-density silicone can be sticky, that’s normal, it should not smell strongly. A shower-curtain odor indicates a dildo is a material like PVC, with plasticizers leaching out.

Top Dual Dildo Choices: Mini Reviews

The following dual dildos by reputable manufacturers (so they’re definitely silicone!) stand out for:

Naked Addiction Dual Density

Pros: Great skin texture. Good suction cup. Tight, squishy balls.
Cons: Not for G-spot stimulation / prostate. Only 1 size.
Price: $59.99

The Naked Addiction “8 Inch” dual-density dildo has just the right amount of skin texture: It offers a touch of skin-line drag, without being either overly slick or too tacky (after it’s lubricated).

With squeezable balls and a soft tip, it’s a very comfortable toy. The Naked Addiction dildo’s average insertable length, 5.5 inches, means it’s not too aggressive vaginally.

Hooray!

My only “eh” is that the Naked Addiction’s tapered head makes it simple to get in, but it doesn’t have the popping ridge (or forward curve) required for good G-spot massage. (The same applies for prostate stimulation: a prominent ridge, a bulb, and/or forward curve are needed to *push* forward and stroke the spot.) So, Naked Adddiction dual-density is an awesome thrusting dildo, but I’ll usually add in a clit stimulator like the Pillow Talk Racy’s rumbly vibes or We-Vibe Melt’s intense air pulse tech for the best fireworks!

Neo Elite silicone dildos by Blush

Pros: Awesome price. Decent realistic balance. Tons of dildo shapes.
Cons: Not the most squeezable silicone. Smaller models are quite flexible.
Price: $23.99 and up: Price increases with the big dildos.

These are the best affordable option: really, really cheap for two layers of platinum silicone. And they still get good reviews: The Neo Elite 7.5 Inch models ($32 and $35) are most popular.

Neo Elite dual density dildos

The 7.5 Inch with Balls gets good-to-glowing reports for both prostate play and anyone with a sensitive G-spot; while the 7.5 Inch no Balls is easier to suction-cup to the wall and to go *deeper* with. It, my favorite Neo Elite, feels so good for gradual stretching, either anally or vaginally (I’m glad I have more than 1!). Great for grinding on, if you have the right suction-cup spot; or just lying back in bed with a good strong vibrator.

The Neo Elite dildo line now includes 9 realistic shapes, reviewed here. Two Neo Elite are truly extra-large. The 10 Inch and 11 Inch’s thicker cores make them more stable, and a better firm ride when you stick them to a smooth floor. (Be prepared, they are both about 2.25 inches diameter: girthy!!!) In contrast, my favorite first anal dildo to recommend is the tiniest Neo Elite, the 6 Inch Tapered: for an easy beginner butt-thrust tool!

VixSkin Mustang & More

Pros: Beloved for anal play. Really squishy outside; good glide. Tons of shapes.
Cons: Premium price. Toy heads are softer than a real-life erection. Fairly flexible.
Price: $82 to $133 (Mustang is $116).

What was the first dual-density dildo? Well: Vixen Creations pioneered the dual-density dildo in 2006, introducing VixSkin silicone.

And, the VixSkin Mustang is the reigning classic dual-layer silicone dildo that’s made in the USA. It’s loved for its super-soft head, which is just enough *pop* when you’re going fast. (This is the nicest pegging dildo besides SquarePeg’s Super-Soft realistics, below.)

VixSkin Mustang and Vixskin Johnny dual density silicone dildos

People who are ultra-sensitive to dildo textures —and thus prefer a slick surface— will find that VixSkin’s unique silicone suits them best (vs. other dual-density dildos). It slides super-well when lubricated, especially with hybrid lube. For me, that slickness reduces the realistic skin feel, but it is a legit preference: and perhaps why VixSkin is so very well-regarded for anal penetration.

Hismith Dual Density Dildos

Pros: OMG squishy-fleshy. Skin-textured, but slick finish = smooth during high-speed sex machine use. Very decent price.
Cons: Black-painted veins look tacky IMO. (Silicone) painted head coloring.
Price: $49.99 to $85 (search for “dual-density dildo”). Use code PR10 for 10% off.

Hismith is the most popular sex / fuck machine maker, and they’ve now improved how realistic their dildo-machines feel with a line of dual-density silicone dildos. Add lube, and the dildos’ very-slick finish is, like, 😲😵😵‍💫 I can only describe in emojis how nice the gliding in-and-out movement feels. Each Hismith dual density has a lot of skin ripples, veins and random bumps, but the smooth finish makes ’em not draggy.

The 9.1 Inch dual-density dildo is a total rush for me: big-headed, soft G-spot stimulation, plenty of girth (my preference is about 2″ diameter mid-shaft, which is large). It feels so, so good. I will warm up first with the Hismith 8.1 inch dual-density dildo, which I’d recommend first for folks who like a more average size. (It’s just a little thicker than the average penis, and the ridge is also 👍👍for G-spot massage.)

Hismith Premium machine favorite dildos - Hismith Dual Density, SquarePegToys Steve

You do not need the sex machine to use these dildos: each one has a metal KlicLok connector that you unscrew to make it a normal suction cup dildo. But, if you are looking to go all in for a 100% automatic (hands-free!!!) dildo session, then the Hismith machine literally takes it up a few levels: steady, consistent penetration. The mechanical thrusting goes on, and on, and on, at speeds from (a) 1 stroke every 10 seconds to (b) hundreds of thrusts per minute—you choose how fast.

Only downside: I don’t like that the Hismith realistic dildos’ heads and veins are colored with a silicone paint. This third layer of silicone gradually wears off with exposure to acidic conditions (like the 4.0 to 4.5 pH of a healthy vagina).

Uberrime Artisan Silicone Dildos

Pros: Hand-crafted. Artisan colors (glittery mica within 3 realistic tones!). Multiple shapes to pick from.
Cons: Not cheap. Most combine realistic & stylized (less realistic) elements.
Price: $89 to $135 (More $ for larger size.)

Stability. Uberrime’s latest dual-density dildos are made to feel consistently erect: bending less with the force of thrusting penetration. Their cores are thicker than most dual-density options: meaning the heads have a bit less squish, but they deliver more pressure for G-spot or prostate stimulation.

Uberrime dual-density dildos vs. hand

The Maxime is IMO the best focused G-spot pressure in a dual-density toy (especially if you don’t want all the bulky size of the Luminous Stud dildo’s head). Meanwhile, the “Teres” dildo has the nicest erect but gliding feel, for in-and-out dildo thrusting: its skin textures are just enough, neither too slick nor too extreme; and it has a very flat head.

Uberrime dildos are hand-made in the US (like VixSkin), and the artisan craftsmanship comes through in the glittery mica-pigmented “flesh” tones of these dual-density dildos. All the models I own have a strong realistic look, but minor non-realistic textures so they’re not exactly penis-replicas: like the Maxime’s smoothed-out, extra-focused ridge.

Other Dual-Shore Dildos, Summary

  • Colours Dual Density by NS Novelties. Classic realistic shapes, the Colours Dual Density dildos are kinda like Neo Elite, but not quite as good. Draggier silicone finish, unfortunately; but if you really like texture, then they may be welcome. The 5″ model is slightly smaller than average penis size. These are not to be confused with ColourSoft dildos, which are all one layer of silicone (that’s in-between the firmness of the Colours Dual’s super-soft outside and firmer core); or with the Colours Pleasures dildos, in firm silicone.
  • Shane Diesel BBC dual-density silicone dildo by NS Novelties, $98.99 best price. Modeled lightly after the porn star, Shane’s silicone dildo here has extreme, jacked-up vein textures that are above and beyond. But, a slicker silicone finish (good news!) between all those bulgy bulgy veins. Shane Diesel dildo has 8.4 inches insertable length, and doesn’t bend too much despite all that length.
  • King Cock Elite: A good effort by a major maker usually known for their half-assed product quality (IMO). King Cock Elite is the first body-safe truly realistic line by Pipedream, and the silicone feels pretty good! It is a tad rubbery. I recommend the $52 King Cock Elite 6 Inch Dildo first. Skip the vibrating models because the vibrations are weak & irritating.
  • Shaft dildos by FemmeFunn: Super-soft and squeezable outside, Shaft dildos are… not a bad pick. Some models (N) have super-sized veins. Model A is my favorite. The quality control could be improved here, as one of mine had black flecks embedded in the silicone, and the maker is cutting cost (labor time) by not vacuum-degassing the core silicone: see the Shaft dual-layer’s air bubbles here.
  • Luminous Dildos by Evolved: The Luminous Stud has long been a favorite for serious impact (on my G-spot) when stuck to a wall. It’s got a huge, popping head. While the Luminous average-size is a solid everyday dildo, at a decent price, and noteworthy if you’d like to “charge” your dildo and have it glow in the dark. The Luminous silicone is tad squishier than Neo Elite Glow dildos, which IMO is an advantage to Luminous. They are clearly mass-produced, in that you can see lil air bubbles inside and surface marks on the soft silicone in some Luminous toys: not a safety issue (since silicone, as a hydrophobic cross-linked polymer, is safe throughout the entire body of the material), just don’t expect VixSkin-level perfection.
  • Tantus dual-density, including Cush: Tantus began making dual-density dildos ca. 2011, following Vixen’s first step in 2006.1 The Cush was a favorite among reviewers 10 years ago: it’s thick with a squishy head, and semi-phallic look. It’s filling and good for use with a clitoral toy alongside, but the Cush’s lower-shaft “lip” is an odd feature that makes it a painful dildo to thrust. Tantus made several realistic double-density dildos for SheVibe after that, which have never been fan-favorites since their silicone is firmer than VixSkin, the epitome of luxurious comfort.
  • Fukena dildos: This vendor, who started on Amazon, has a huge range of silicone dual-density dicks, with very precise size specifications for each. Fukena has stopped using silicone paint to color their toy heads, which shows they do respect customer complaints (it rubbed off in some cases). The Archer looks like the best choice for a smoother model, but based on my experience with the Quarterback, the soft silicone from the factory Fukena uses has a very matte feel, meaning all the skin lines grab. If you like plenty of texture, they may be your bag. If you are sensitive to drag, avoid.
  • What about the RealCock2?!? This $600 ultra-realistic dildo is a lot. A lot of money, a lot of bulky base, a lot of moveable silicone. I was in love when I first got the RealCock 2 Dirk: like, how oooh so squeezable its thick skin layer is. The silicone paint job is better done than with cheaper silicone dildos, too; it doesn’t fade. Then, over time, I got frustated with the amount of stress the RealCock2’s extra extended base (and heavy balls) put on my hand and wrist; while it was difficult to remove the Realcock’s gauze-lined Vac hole from my sex machines. (The dildo arrives with non-removable gauze fixed around that hole.) Eventually I stopped using my RealCock since it’s such a pain to jerk, and when I came back after having sealed it in a bag for 6 months, boils had popped up all over the ball sack. Like, blisters. It’s creepy. (Other silicone dildos in the same bag saw no damage.) So, I think whatever’s inside the RealCock’s “floating testicles” maybe isn’t the most stable material. The RealCock 2 triple-density dildo was fun for a while. But really, there are soft dual-silicone toys that deliver the same orgasms and good realistic feel—without being so clunky & expensive.

And, there’s one other dual-layer dildo category: posable silicone dildos are silicone outside, with a metal core underneath. These toys include Dr. Skin Silicone (very hard outside for a dual-layer toy), Naked Addiction David & Andrew (softer outside), Strap-On-Me Dual-Density Bendable (kinda soft, not super-soft), and New York Toy Collective posable dildos.

There’s also the Lovehoney Happy Rabbit Dual Density vibrator, which is firm silicone outside, not traditional dual-density.

Last, “SilExPan” and “SilExD” dildos are safe silicone outside, but are NOT a good choice if you want a realistic feel. May be called by other names like “Fleshstixxx.” The outside silicone is hard, and the inside is a mystery material that gets squishy when you heat such a dildo. If you find a dildo where the product description advises you to “heat it in the microwave,” then it’s part of this less-realistic SilExD category.

Avoid These Dual-Density Dildos: Safety

The following dual-D dildo lines are not made of body-safe silicone. Avoid them for safety reasons.

  • Au Naturel by Blush.
  • “Ultraskyn” dildos like the “Perfect D,” by Doc Johnson.
  • Lifelike Lover Classic Dual-Density Ultra Realistic Dildo by Lovehoney. TPE, which Lovehoney disguises by calling “soft plastic.”

Super-Soft Dildo Alternatives

Dual-density silicone is considered the gold standard for realism: a dual dildo’s firm core will bend less, giving a more erect effect. But, in some cases, 100% super-soft silicone (no firm inner core) is advantageous:

  • Extra-large toys (say, dildos 2.5 inches diameter / 8 inches circumference and bigger), where pure soft silicone is gentler.
  • Anal play: super-soft silicone toys were originally made for anal (by SquarePegToys, like in the exceptional Egg Plug; then Bad Dragon), where many users do like a good squishy pounding.

The best super-soft realistic makers today are SquarePegToys (originator of 100% SuperSoft silicone, in 2006): see Leo and Steve; and Mr. Hankey’s Toys’ custom-blended 75% Soft firmness (Nick Capra dildo review here), popular for both vaginal and anal use, especially for thick dildos, where the soft silicone is less flaccid-floppy.

    • Hi, thanks for reading! I agree, I was surprised at the shiny-ness; and it was off-putting to me at first because I associate a shiny look with oily TPE toys. Thankfully, these are definitely silicone, just with a very smooth finish;

      the outside is an 00-30 Shore durometer, so they’ll be as squishy as classic dual-density toys like VixSkin.

      My Hismith machine full review, this section,has a bit more on these toys;

      I can post a slightly longer “squish” clip if you’d like. Do you have any preference for Twitter, Instagram, or YouTube? (Hopefully I can still post on YT, they do *not* like realistic dildos over there and I keep getting warnings about how my account will be be removed if I get one more strike!!!)
