High-tech sex toys keep getting smarter (NSFW, seriously)

Warning: This gallery contains sexual content and descriptions not suited for children. 

Vibrators have always vibrated, but technology is taking today's sex toys a lot further. We're talking 3D-printed robot masturbation aids, interactive Kegel exercisers and more racy gadgets. Some of them look so stealth you can't even tell they're about sex.

As part of Turned On, CNET's special report exploring the intersection of sex and technology, we've updated this gallery to include some of the latest smart toys hitting bedrooms and beyond.

Pictured here is the Lovenuts, a vibrator that can also be used as a flashlight. 

This gallery was originally published June 17, 2016.

The Lovenuts was an undercover vibrator previously seeking funding on Indiegogo under the Indiegogo After Dark umbrella. It looked like a little acorn, fits in your hand and can be used as a flashlight. 

Once paired with an app on your phone, it's a discreet wireless, remote-controlled vibrator. 

The i.Con Smart Condom, which markets itself as the "world's first smart condom," is actually a ring that fits over a boring, dumb condom and claims to track the exercise of your man bits, as well as detect chlamydia and syphilis.

The ring, first announced in July 2016, is still, three-plus years later, just a preview item at British Condoms for £59.99 (about $74, AU$97) with an unknown release date. (The company did not respond to requests for comment.)

The Lioness app-enabled vibrator has a stated goal of offering "new ways to learn and explore your own body for better pleasure and health." The Lioness uses temperature, motion and pressure sensors to collect information on how your body responds.

The Ose from company Lora DiCarlo taps robotics to provide women with hands-free blended orgasms that involve both the clitoris and G-spot. It does this through microrobotics meant to mimic human touch in place of vibrations. It is not yet available for purchase.

The MysteryVibe Crescendo vibrator can be contorted into multiple shapes, charges wirelessly and is crafted from silky high-grade silicone.

It has six motors, each of which can be controlled individually from the MysteryVibe app. The app also lets people create custom vibration patterns for themselves or a partner. 

At IFA 2019, where British sex toy company MysteryVibe has launched products in years past, Katie Collins wrote that the event "shows CES how to exhibit sex toys in a classy, educational way."  

Two women invented the Eva wearable women's toy as an answer to male-oriented, vibrating rings. After a sensational run on Indiegogo, the Eva won praise for its hands-free, female-friendly design.

The device charges via USB. It's supposed to be worn during intercourse and the site claims it gives "vulvas the clitoral stimulation they want during sex." With its retractable "arms," it is meant to stay in place and stimulate the clitoris.

Dame also produces the Fin, a small vibrator made to be worn between the fingers. Water-resistant, it too is rechargeable via USB.

The Fiera Arouser for Her from Nuelle is an intimacy enhancer meant to help women become aroused by providing stimulation and gentle suction.

The Krush is a part of OhMiBod's Lovelife line of products. It's meant to help women evolve "smarter Kegel fitness" routines.

The Svakom Siime Eye is an internet-connected, camera-equipped vibrator. However, UK-based security services firm Pen Test Partners said in 2017 that the smart sex toy is vulnerable to hacking.

The $249 (£193, AU$ 314) device works with an app that lets people shoot pictures and videos and save them to devices like phones or laptops. Unfortunately, researchers found that anyone within Wi-Fi range who figures out your password can access your video stream. 

Abyss Creations' robotic head can be attached to silicone RealDoll body. Here's what it's like to chat with a sexbot called Harmony. 

PicoBong's Transformer is gender-neutral, according to its maker.

The toy has a 4-inch (10-centimeter) vibrator on each end made from body-safe silicone and costs $129 (£100, AU$162). For more details, check out the description on PicoBong's site.

The high-tech male masturbator seen here is the Kiiroo Onyx. Kiiroo has partnered with BaDoinkVR, a porn production company that specializes in VR porn, to sync its product with the VR experience in "real time." That means every thrust or grind you see, you feel too. 

Both companies also offer slightly unconventional sex-ed videos, as well as programs "aimed at improving sexual technique." 

Kiroo's Fleshlight Launch takes male masturbation to another level by removing the need for hands. Just insert a regular Fleshlight into the device and it does all the work for you at 180 strokes per minute. It also syncs with Kiiroo videos and interactive content from the company's partners.

This next phase of the Motorbunny, described as a "straddle-style personal pleasure machine," will be a web-based component that lets people send their personal code to other users -- either people they know or strangers. 

The Lush by Lovense is an insertable sex toy that can be controlled by a partner over short range via Bluetooth -- or far away via an iPhone app or Android app. This sort of long-distance contact via gadgets is apparently known as teledildonics. 

The Lush companion app lets you customize the power and strength of vibrations (left), chat with a partner across the world (center), and save and replay your favorite patterns.

PicoBong has four app-enabled toys that work with its Remoji app: the Blowhole, a male vibrator; the Diver, an egg-shaped vibe; the Lifeguard, a ring vibrator; and the Surfer, a vibrating plug.

Small batteries fuel the Hello Touch X wearable vibrator, billed as the smallest of its kind available.

The design features two ultracompact "pleasure pods," or silicone fingertips with interchangeable vibration or electrostatic stimulation. Users control the device using a toggle on a wristband. It can be recharged via USB. It's made of medical-grade silicone and is phthalate-free. 

For women, pelvic floor strength has several advantages, including, for many, better sex. Billed as the "world's first smart Kegel trainer," this device-and-app combo from Minna essentially works as a personal trainer for Kegel muscles, measuring and tracking pelvic floor exercise.

Another Minna product, Limon, adjusts its vibrations based on how hard it's squeezed. Beyond that, people can compose, record and play back custom vibration patterns. The insertable toy is made of medical-grade silicone and is USB rechargeable.

Available for purchase for $129 (£108, AU$174), the Perifit is a pelvic floor workout device with an accompanying iOS or Android app. Made with medical-grade silicone, the Perifit is meant to be inserted and then used similar to a "gaming controller" to complete the workout programs through the app by squeezing your pelvic floor muscles. 

Like many sex toys, the Lelo Tiani (including a "24k" version, shown here) has a remote control. As the control, dubbed SenseMotion, tilts or moves more quickly, the vibrator's frequency changes.

Lelo offers five other remote-controlled vibrators, including a new version of the Tiani.

Autoblow 2 is described by creator Brian Sloan as a "robotic oral-sex simulator for men." A wildly successful Indiegogo campaign (as in, more than 600 percent of its initial funding goal) has led to lots of attention, as well as an interesting set of demo animations. It must be plugged into the wall and features interchangeable sleeves that can used with water-based lubricant.

The Pulse from Hot Octopuss is more than just a deliverer of high-amplitude waves aimed at stimulating the male anatomy. It also has a pair of adjustable wings, allowing the device to expand as the guy does. 

The Pulse 3 Duo has a vibrating underside for use by couples. It also has a remote control.

The Tenga 3D masturbation tube won a Red Dot Award in product design in 2012, and it's easy to see why. Each one looks like a piece of 3D-printed art. And that's exactly what they are.

The all-white sleeves are made from flexible, 3D-printed antibacterial plastic, and each features a unique texture (say, twisted spirals, or stacked, triangular patterns) to create unique sensations once the sleeve has been flipped inside out.

Tenga is known for other sex toys that could double as art like the Easy Beat Egg or the Flex series. The 3D series sleeves are the only ones that come with their own stand, though.

Tenga also offers an online fitting tool aimed at men. Enter your size and other personal information, and Tenga recommends the ideal sex toy for you.

At CES 2019, the biggest topic, almost by accident, was sex tech. In August, the company that runs CES announced it was opening show floor applications to sex tech companies under health and wellness after a months-long debate.

We expect to see numerous companies taking advantage of the opening in January 2020.
