  • Sex toys use body-safe materials or coatings over semi-body-safe materials to create a device to go inside of you.

  • Sex toys feel good as they arouse your genitals and send pleasure signals to your brain, making blood rush to your genitals and your toes curl.

You pull your favorite toy out of your nightstand drawer, squirt a bit of lube on it, and allow the toy to work its magic on your body. Your mind transports to another universe where you only think about the pleasurable sensations running up and down your spine and pulsating at your genitals. Eventually, you orgasm, take a moment to breathe, then clean up and go to bed.

How did that happen? This little toy overtakes your body, and you likely don't even know the first thing about how it works. As far as most people notice, you hit a button, and — wow — it feels good. Honestly, this is totally valid, as we don't need to know why it feels good, as long as it does feel good.

Understanding the science behind pleasure and how sex toys work allows you to unlock a new dimension of understanding your body and the toys you put into it.

Understanding Intimate Toy Mechanics

In the world of human sexuality, the use of sex toys evolved from a secretive and taboo topic into an openly discussed facet of intimate relationships. These devices, designed to enhance pleasure and stimulate desire, are a testament to human ingenuity and creativity. Have you ever thought about the mechanics of sex toys? You likely press the little button, then sit back while your toy works some magic.

Sex toys have fascinating design, functionality, and various ways to deliver gratification. While the design of these toys often comes from experts of human pleasure, it's good to have a basic understanding of how some functionalities work.

Vibrating

Vibrators are among the most common and well-loved sex toys, and their mechanics are relatively simple yet highly effective. The classic vibrator intended for clitoral pleasure isn't the only type of toy that vibrates, though. Prostate massagers, cock rings, and other toys bring an element of vibration for sensation. Even your phone vibrates!

At the core of a vibrator lies an eccentric weight, an unbalanced mass that spins or oscillates when powered. As this weight rotates, it generates vibrations, which transfer to the surface of the toy. The user controls the intensity and pattern of these vibrations through buttons or remote control, allowing for a customized experience ranging from gentle pulsations to intense tremors.

Dildos

Dildos, designed to mimic the look and feel of a human penis, are non-vibrating sex toys that rely on a more straightforward mechanical design. These toys contain body-safe materials like silicone, rubber, or glass. The user manually controls the thrusting and movement of the dildo, simulating the sensations of intercourse. Some dildos incorporate a suction cup base for hands-free enjoyment, adhering securely to flat surfaces.

Some dildos feature no mechanical features and work manually. Others have advanced features to vibrate, rotate, or thrust.

Thrusting

Thrusting sex toys have a motor and a linear actuator. The linear actuator is a device that converts the rotational motion of the motor into a linear back-and-forth movement, like thrusting. Attached to the linear actuator, there's a thrusting arm or rod that extends into the toy's main body. This arm is often made of a sturdy yet flexible material like silicone or plastic.

When the motor activates, it causes the linear actuator to move the thrusting arm back and forth. This motion mimics the thrusting action of a human partner during intercourse. Users have the ability to control the speed and depth of the thrusting motion. Users control this through buttons, dials, or remote controls, allowing users to tailor the experience to their liking.

Rotating

Rotating sex toys feature a rotating shaft that creates circular motions internally for G-spot pleasure. Most rotating sex toys allow the user to control the speed and direction of the rotation. These settings adjust using buttons, dials, or remote controls. Users choose whether they want the shaft to rotate clockwise or counterclockwise and adjust the speed according to their preferences.

At the heart of the rotating mechanism is a small electric motor. This motor is responsible for generating the rotational movement. The motor's power transmits through a set of gears, which converts the linear motion of the motor into the rotational motion needed for the toy's shaft. Connected to the gears, there's a shaft or rod that extends into the main body of the toy. This silicone or plastic rotates as the motor turns the gears.

The rotating shaft has a texture or contoured surface to enhance internal stimulation. As the shaft rotates, it provides a more natural and lifelike sensation, similar to the movement of a partner during intercourse. Many of these toys are rabbit vibrators, which combine both penetration and clitoral stimulation. Rabbit vibrators have a separate appendage, often shaped like rabbit ears, a dolphin, or other creatures, which are responsible for clitoral stimulation.

Suction and Air-Pulse Toys

Suction and air-pulse toys mimic oral sex with their unique mechanism. These devices create a gentle vacuum around the clitoris and utilize pulsating air in waves of pleasure. The airwaves stimulate the clitoris without direct contact, offering a sensation that many find exceptionally intense and satisfying. Adjustability and customization options are common features in these toys, allowing users to fine-tune the intensity to their liking.

The original suction toy is the Womanizer — a new kind of sex toy that took the world by storm. According to Flore Cherry at Vogue, "In 2012, Michael Lenke, a German genius with a passion for DIY hacks, discovered — with great shock — that the majority of women have difficulty achieving an orgasm. He then embarked on a crazy invention dedicated to lowering this statistic. He hijacked an aquarium pump, assembled his first prototypes, and conducted some tests with his wife, Brigitte. Despite her initial doubt, she predicted that this ultra-performing object would be 'a worldwide success'. Time proved them right."

The core of the air suction mechanism is an air chamber or cavity located at the tip of the sex toy. This chamber has a soft, body-safe silicone or rubber nozzle that comes into contact with the user's skin. Within the air chamber, there's a flexible diaphragm or membrane made of silicone or another pliable material. This diaphragm moves in response to changes in air pressure.

A small air pump or motor is responsible for creating changes in air pressure within the chamber. When activated, the pump generates controlled pulses or waves of air, creating a suction effect within the chamber. To regulate the intensity of the suction, these toys often include an air release valve. This valve allows air to escape from the chamber, adjusting the strength of the suction based on the user's preferences.

Many air suction toys offer various intensity levels and patterns of suction. Users control these settings through buttons, dials, or smartphone apps, depending on the toy's design.

To use these toys, the user places the nozzle of the toy over the desired erogenous zone, such as the clitoris. The nozzle forms a seal with the skin, creating an airtight environment within the air chamber. When the user activates the toy, the motor or air pump begins to generate pulses of air. These pulses cause the diaphragm or membrane within the air chamber to move in and out, creating a gentle suction effect on the clitoris or the targeted area.

As the diaphragm moves, it alternately increases and decreases the air pressure within the chamber. This mimics the sensation of someone gently sucking and releasing the area. The resulting sensations range from subtle to intense, depending on the chosen intensity level and pattern.

The key advantage of air suction mechanisms is that they provide stimulation without direct contact, which is especially appealing to individuals who are sensitive or prefer a different type of sensation compared to traditional vibrators or friction-based toys. It offers a unique and often highly pleasurable experience.

Remote Control and App Connectivity

With the advancement of technology, many sex toys feature remote control through dedicated apps on smartphones or remote controls. These wireless options offer a level of intimacy and excitement for couples looking to explore pleasure together, regardless of physical distance. App-connected sex toys allow partners to interact in real time or even share control, adding a new dimension to long-distance relationships and intimacy.

Remote Control

Remote control sex toys typically use wireless communication technologies such as Bluetooth, radio frequency (RF), or infrared (IR) to establish a connection between the toy and the remote control. To get started, the user pairs the remote control with the device. This often involves pressing specific buttons or following instructions in the toy's manual. Once paired, the two devices communicate with each other.

The remote control has buttons or dials that allow the user to control various functions of the sex toy. These functions may include adjusting the intensity, changing vibration patterns, or activating specific modes. Users manipulate the toy's settings in real time using the remote control, providing a more hands-on and immediate experience. This is especially popular for couples looking to enhance intimacy.

App-Control

App-controlled sex toys typically use Bluetooth technology to connect with a smartphone or tablet. Many modern sex toy manufacturers develop dedicated apps for their products, which are available in the app stores. To establish a connection, the user needs to open the app and follow the pairing instructions provided within the app. This often involves putting the toy into pairing mode and allowing the app to discover and connect to the device.

Once paired, the user controls various functions of the sex toy through the smartphone app. The app usually offers a user-friendly interface with options to adjust vibration intensity, choose from pre-programmed patterns, or create custom patterns.

App-controlled toys often come with additional features such as remote control by a partner, long-distance control over the internet, and the ability to sync the toy's vibrations with music or voice input for a more immersive experience. App-controlled sex toys are particularly popular for couples in long-distance relationships as they offer a way to maintain intimacy and connectivity over distances.

Power Sources

Sex toys have been electric or battery-operated for over 100 years. Battery-operated sex toys became the standard in the mid-20th century, with the exception of some toys that need to be plugged into the wall. Now in the 21st century, a rechargeable lithium-ion battery is standard. Most sex toys come with a unique charger that slips past the waterproof silicone cover and brings life to your toy.

The power source serves as the heartbeat of the device, delivering the energy required to drive the various mechanisms responsible for stimulation. These power sources are typically discreetly tucked away within the toy's body, ensuring a seamless and uninterrupted experience for the user.

Materials Matter: The Role of Body-Safe Materials

The materials used in sex toys are of utmost importance for safety, comfort, and hygiene.

Pleasure Physiology: What Happens in the Body

Sexual pleasure is a profound and complex experience that involves both physical and psychological elements. With the advent of innovative sex toys, individuals and couples have access to new dimensions of pleasure. The physiology of human pleasure is fascinating. How do sex toys enhance this complex experience?

The Brain

The pleasure derived from sexual experiences, whether with a partner or through the use of sex toys, largely hinges on the brain's intricate mechanisms. The brain is the command center for interpreting sensory signals and generating pleasurable sensations. During sexual arousal, various brain regions, including the hypothalamus, amygdala, and prefrontal cortex, work in harmony to process sensations, emotions, and thoughts, creating a state of heightened pleasure.

Inspired by a lack of touch during the COVID-19 pandemic, a group of scientists at Columbia University began studying the brain's reaction to touch on sensitive parts of the body. According to results published in March 2023, touch on the skin directly influenced reward centers in the brain. Test subjects even got turned on by the touch in some sensitive areas! You don't just feel pleasure from touch; your brain actually rewards you.

How Sex Toys Enhance Pleasure

Sex toys stimulate erogenous zones, such as the genitals, nipples, and other sensitive areas of the body. When these areas receive stimulation, a cascade of physiological responses occurs, intensifying pleasure. Sexual arousal, whether initiated by a partner or a toy, leads to an increase in blood flow to the genitals. This engorgement results in heightened sensitivity, making touch and stimulation more pleasurable.

As sexual excitement builds, the brain releases neurotransmitters like dopamine, oxytocin, and serotonin. These chemicals create feelings of pleasure, bonding, and relaxation. Sex toys target nerve-rich areas, such as the clitoris, G-spot, or prostate. These nerve endings respond to stimulation by sending pleasure signals to the brain.

During sexual arousal and stimulation, muscles throughout the body, including the pelvic floor muscles, tense up. The subsequent release of tension leads to pleasurable sensations and even orgasms.

Why It Feels Good

The sensation of pleasure experienced during sexual activities, including the use of sex toys, serves both physiological and evolutionary purposes. Pleasure encourages sexual activity, increasing the likelihood of procreation and the survival of the species.

Sexual pleasure triggers the release of endorphins, which act as natural painkillers and stress relievers, promoting overall well-being. The release of oxytocin, often referred to as the "love hormone," fosters emotional bonding and trust between partners. The positive feelings associated with sexual pleasure alleviate depression, anxiety, and insecurity.

Sex toys add an extra dimension to these natural processes. They provide targeted and consistent stimulation, helping individuals and couples explore their desires, intensify arousal, and experience new sensations. The novelty and versatility of sex toys also contribute to sexual satisfaction by keeping intimacy exciting and fulfilling.

The physiology of pleasure during sexual experiences, whether with a partner or through the use of sex toys, underscores the remarkable capabilities of the human body and brain. The intricate interplay of nerves, hormones, and emotions serves to enhance intimacy, improve overall well-being, and foster deep connections between individuals. Sex toys have expanded the possibilities for pleasure, offering a safe and exciting way to explore and celebrate the rich tapestry of human sexuality. Ultimately, understanding the science behind pleasure leads to a more fulfilling and satisfying intimate life.
