The Venus for Men, previously sold as the Venus 2000, is a self-actuated masturbation aid for men [1] [2] [3] [4] that applies sexual stimulation using a mechanism outwardly similar to a milking machine. The machine works with or without an erection. [5] Metro has described it as a sex toy "for the serious onanist". [6] In addition to masturbation, the machine may also be used for orgasm control practices such as edging or forced orgasm.
The Venus II was invented by Rick Gellert, with the assistance of Valentin Tsitrin, a Russian engineer. [7] Gellert has written:
...It seems male desire for sexual activity ranges from needing an orgasm once in many weeks to wanting several in a day. [...] after hundreds of variations, I developed a product unique enough so that I was awarded patent #5501650. [8]
The device was marketed as Venus II from October 1993 to April 1998. Gellert and Tsitrin presented their device to Abco Research Associates in 1993 (also manufacturer of the Sybian), and Abco helped them launch and market it. As a result, Abco became the primary marketer of the Venus II. [8] In April 1997, Abco purchased the Venus II patent along with all manufacturing and marketing rights. This led to the launch of an improved version, Venus 2000. [8]
In 2014, Abco modified the name of the product to Venus by Sybian. They also refer to the product as Venus For Men.
The design of the device was covered by U. S. patent 5501650. It consists of a main box linked to a cylindrical "receiver" that fits over the penis by a connecting hose. The "receiver" superficially resembles the teat cup of a milking machine, and contains an inner and outer chamber separated by a cylindrical flexible rubber liner. Only the outer chamber is linked to the main box, with the inner chamber open at one end, ready for the insertion of the penis. Unlike a milking machine, the other end of the Venus 2000's inner chamber is not connected to a suction hose, but instead covered by a cap that contains a one-way valve that leads to the open air.
The main box contains a gearmotor which drives a reciprocating diaphragm. Air moves to and from the outer chamber of the "receiver" via the hose. The device works by sucking in the shaft of the user's penis when the tip is placed against the receiver's opening before activation, using the partial vacuum created by the removal of air from the inner liner via the one-way valve at the closed end of the receiver. The amount of air in the system is adjustable and determines the stroke length. Most users can adjust it to move the full length of the shaft. [9] A significant amount of personal lubricant is needed to be added within the liner for the machine to operate correctly.
The system is controlled during operation by two small control boxes. One of them is an electrical control box, with a speed adjustment knob, attached to the main box by an electrical cable. The other is a pneumatic control box, linked by a rubber tube to the diaphragm chamber, and has two push-buttons, one to add air to the system, and the other to remove air from the system. The final adjustment possible is an internal adjustment that can be used to change the amplitude of the pumping motion, but this is not available in operation, as adjusting it requires the main box of the machine to be dismantled and reassembled.
For best operation, all the components of the "receiver" need to be sized for the penile dimensions of the user. To this end, the plastic receiver bodies are available in a variety of tube lengths and diameters, and the rubber liner material also comes in a variety of diameters.
Aqua-Lung was the first open-circuit, self-contained underwater breathing apparatus to achieve worldwide popularity and commercial success. This class of equipment is now commonly referred to as a twin-hose diving regulator, or demand valve. The Aqua-Lung was invented in France during the winter of 1942–1943 by two Frenchmen: engineer Émile Gagnan and Jacques Cousteau, who was a Naval Lieutenant. It allowed Cousteau and Gagnan to film and explore underwater more easily.
A sex toy is an object or device that is primarily used to facilitate sexual pleasure, such as a dildo, artificial vagina or vibrator. Many popular sex toys are designed to resemble human genitals, and may be vibrating or non-vibrating. The term sex toy can also include BDSM apparatus and sex furniture such as sex swings; however, it is not applied to items such as birth control, pornography, or condoms. Alternative terms for sex toy include adult toy and the dated euphemism marital aid. Marital aid also has a broader meaning and is applied to drugs and herbs marketed to enhance or prolong sex.
A cock ring or cockring is a ring worn around the penis, usually at the base. The primary purpose of wearing a cock ring is to restrict the flow of blood from the erect penis to produce a stronger erection or to maintain an erection for a longer period of time. They are sometimes used as medical devices, on their own or in conjunction with a penis pump to assist in the management of erectile dysfunction. Genital adornment is another purpose, as is repositioning the genitals to provide an enhanced appearance.
A sex position is a positioning of the bodies that people use to engage in sexual intercourse or other sexual activities. Sexual acts are generally described by the positions the participants adopt in order to perform those acts. Though sexual intercourse generally involves penetration of the body of one person by another, sex positions commonly involve non-penetrative sexual activities.
A Sybian, or Sybian saddle, is a type of masturbation device, consisting of a hollow saddle-like seat containing two electric motors, motor speed controller boards, gearing, pulleys, and a platform on cranked axles such that a ridge on the top of the unit can be made to vibrate through a range of speeds as set using a wired external hand controller, and an upward-pointing shaft set on an angle through the ridge can be made to rotate at speeds of up to several hundred revolutions per minute, again by use of the wired remote control. Flexible molded attachments are usually supplied, fitting over the vibrating ridge and shaft which mostly have integrated dildos on their top. In use, the rider inserts the dildo into a body orifice for internal stimulation while applying pressure on the vibrating ridge with their external erogenous parts.
The cervical cap is a form of barrier contraception. A cervical cap fits over the cervix and blocks sperm from entering the uterus through the external orifice of the uterus, called the os.
A diving regulator or underwater diving regulator is a pressure regulator that controls the pressure of breathing gas for underwater diving. The most commonly recognised application is to reduce pressurized breathing gas to ambient pressure and deliver it to the diver, but there are also other types of gas pressure regulator used for diving applications. The gas may be air or one of a variety of specially blended breathing gases. The gas may be supplied from a scuba cylinder carried by the diver, in which case it is called a scuba regulator, or via a hose from a compressor or high-pressure storage cylinders at the surface in surface-supplied diving. A gas pressure regulator has one or more valves in series which reduce pressure from the source, and use the downstream pressure as feedback to control the delivered pressure, or the upstream pressure as feedback to prevent excessive flow rates, lowering the pressure at each stage.
Erotic sexual denial is the practice of refraining from sexual experiences in order to increase erotic arousal and/or tension. It is commonly used as sex play within the context of a dominance and submission relationship, though it can also be a solo practice. The prohibited experience can be narrowly or broadly defined and banned for a specific or indeterminate length of time, depending on the practitioner. The experience withheld can be any favored or desired sexual activities, such as specific acts or positions, provided it is something the practitioner wants.
Fingering is sexual stimulation of the vulva or vagina by using the fingers. Vaginal fingering is legally and medically called digital penetration or digital penetration of the vagina. The term "digital" takes its significance from the English word 'digit', which refers to a finger, thumb, or toe. Fingering may also include the use of fingers to stimulate the anus.
A strap-on dildo is a dildo designed to be worn, usually with a harness, during sexual activity. Harnesses and dildos are made in a wide variety of styles, with variations in how the harness fits the wearer, how the dildo attaches to the harness, as well as various features intended to facilitate stimulation of the wearer or a sexual partner. Strap-on dildos are most frequently used by lesbian women, but can be used by people of any gender or sexuality.
Chastity belts are a type of chastity device used in BDSM as part of the practice of orgasm denial, to prevent the wearer from engaging in certain types of sexual activity without the permission of the dominant, who acts as "keyholder", possessing the key that unlocks the chastity belt. Without access to the key, the wearer usually cannot take off the chastity belt or device. Dominants may also enjoy long-distance chastity with their sub by keeping the key in a third location that the chastity wearer cannot access by themself.
A vibrator, sometimes described as a massager, is a sex toy that is used on the body to produce pleasurable sexual stimulation. There are many different shapes and models of vibrators. Most modern vibrators contain an electric-powered device which pulsates or throbs. Vibrators can be used for both solo play and partnered play by one or more people. Devices exist to be used by couples to stimulate the genitals of both partners. They can be applied to erogenous zones, such as the vulva, vagina, penis, scrotum, or anus, for sexual stimulation, for the release of sexual frustration and to achieve orgasm. Vibrators may be recommended by sex therapists for women who have difficulty reaching orgasm through masturbation or intercourse.
A clitoral pump is a sex toy designed for sexual pleasure that is applied to the clitoris to create suction and increase blood flow and sensitivity. A clitoral pump is designed to be used on the entire external clitoris including the clitoral hood. Other designs of pump exist for the labia, the entire vulva and, in some cases, the nipples.
Non-penetrative sex or outercourse is sexual activity that usually does not include sexual penetration. It generally excludes the penetrative aspects of vaginal, anal, or oral sex, but includes various forms of sexual and non-sexual activity, such as frottage, manual sex, mutual masturbation, kissing, or cuddling. Some forms of non-penetrative sex, particularly when termed outercourse, include penetrative aspects, such as penetration that may result from forms of fingering or oral sex.
Masturbation is a form of autoeroticism in which a person sexually stimulates their own genitals for sexual arousal or other sexual pleasure, usually to the point of orgasm. The stimulation may involve the use of hands, everyday objects, sex toys, or more rarely, the mouth. Masturbation may also be performed with a sex partner, either masturbating together or watching the other partner masturbate.
An artificial vagina is a device designed to imitate the vagina as well as sometimes the vulva. To achieve this, it will generally be made of a soft material, lubricated, and occasionally heated.
A sex machine is a mechanical device used to simulate human sexual intercourse or other sexual activity.
David Lee Lampert was an American sex toy pioneer.
Yoni massage or yonic massage, derived from the word Yoni, a representation of the vulva which symbolizes the goddess Shakti, is a type of Tantric full-body massage. It primarily focuses on the labia, clitoris, G-spot, uterus, the breasts, the anus and other erogenous zones. Yoni massage is the female equivalent of a Lingam massage. The massage is viewed as therapeutic and is sometimes used as a method of relieving tension, pain, or general discomfort of the vagina. It has been claimed by some practitioners to be helpful to achieve fertilisation, although there is no scientific support for this claim.
