Clitoral Pump
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 (both minora and majora), the entire vulva and, in some cases, the nipples. The clitoral pump, like the penis pump, may be used for temporary effect prior to, or during, masturbation or other sexual activity. The clitoral pump is not designed to be applied to the vaginal opening nor the inside of the vagina, since it may cause injuries. The use of a clitoral pump can also help strengthen the pelvic floor muscles and retain vaginal lubrication which can reduce with age. Their use is often recommended by physicians for treating female sexual problems connected with anorgasmia. Improved blood flow to the genitals may be achieved through regular use of the device.

Sex Toy
A sex toy is an object or device that is primarily used to facilitate human 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 slings; 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. Sex toys are most commonly sold at sex shops or online, but they may also be sold in a pharmacy or chemist store, a pornographic store, a head shop, or a department store. Sex toys are available in almost all countries for males and females. Types Erotic electrostimulation Another form of sex toys for both men and women are those for erotic electrostimulation. Ero ...

Sexual Stimulation
Sexual stimulation is any stimulation, stimulus (including bodily contact) that leads to, enhances and maintains sexual arousal, and may lead to orgasm. Although sexual arousal may arise without physical stimulation, achieving orgasm usually requires physical sexual stimulation. The term ''sexual stimulation'' often implies stimulation of the sex organ, genitals, but may also include stimulation of other areas of the body, stimulation of the senses (such as sight or hearing) and mental stimulation (i.e. from reading or sexual fantasy, fantasizing). Sufficient stimulation of the human penis, penis or clitoris usually results in an orgasm. Stimulation can be by self (e.g., masturbation) or by a sexual partner (sexual intercourse or other Human sexual activity, sexual activity), by use of objects or tools, or by some combination of these methods. Some people practice Edging (sexual practice), orgasm control, whereby a person or their sexual partner controls the level of sexual stimu ...

Orgasm
Orgasm (from Greek , ; "excitement, swelling") or sexual climax is the sudden discharge of accumulated sexual excitement during the sexual response cycle, resulting in rhythmic, involuntary muscular contractions in the pelvic region characterized by sexual pleasure.Se133–135 for orgasm information, anpage 76for G-spot and vaginal nerve ending information. Experienced by males and females, orgasms are controlled by the involuntary or autonomic nervous system. They are usually associated with involuntary actions, including muscular spasms in multiple areas of the body, a general euphoric sensation and, frequently, body movements and vocalizations. The period after orgasm (known as the refractory period) is typically a relaxing experience, attributed to the release of the neurohormones oxytocin and prolactin as well as endorphins (or "endogenous morphine"). Human orgasms usually result from physical sexual stimulation of the penis in males (typically accompanying ejaculat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dildo
A dildo is a sex toy, often explicitly phallic in appearance, intended for sexual penetration or other sexual activity during masturbation or with sex partners. Dildos can be made from a number of materials and shaped like an erect human penis. They are typically about the average length of an erect penis, , but some may be longer. A dildo's circumference is typically . Description and uses General A dildo is an object usually designed for sexual penetration of the vagina, mouth, or anus, and is usually solid and phallic in shape. Penis prosthetic aids, known as "extensions", are not considered dildos. Some include penis-shaped items clearly designed for vaginal penetration, even if they are not true approximations of a penis. An anal dildo is intended for repeated anal penetration, to be distinguished from a butt plug which is flanged with the intent of remaining in place. People of all genders and sexual orientations use these devices for masturbation or other sexual activ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clitoral Enlargement Methods
Clitoral enlargement methods are forms of body modification that have the potential to enhance the size of the clitoris and increase sexual pleasure. Clitoral enlargement can be accomplished through a variety of means, each potentially having certain side effects and risks. The congenital or acquired medical condition known as clitoromegaly or macroclitoris contrasts intentional enlargement of the clitoris, though any abnormal enlargement of the clitoris is sometimes referred to as ''clitoromegaly.'' Purpose A very small clitoris may not get adequate pleasure from sexual acts that can directly stimulate the clitoris, such as the coital alignment technique, and may therefore choose to enlarge the clitoris to increase pleasure. Women with normally sized clitorises may wish to increase the size to increase pleasure or to appear more attractive. The clitoral pump, like the penis pump, may be used prior to or during masturbation for temporary effect. Some testosterone-altered female bo ...

Plastic
Plastics are a wide range of synthetic or semi-synthetic materials that use polymers as a main ingredient. Their plasticity makes it possible for plastics to be moulded, extruded or pressed into solid objects of various shapes. This adaptability, plus a wide range of other properties, such as being lightweight, durable, flexible, and inexpensive to produce, has led to its widespread use. Plastics typically are made through human industrial systems. Most modern plastics are derived from fossil fuel-based chemicals like natural gas or petroleum; however, recent industrial methods use variants made from renewable materials, such as corn or cotton derivatives. 9.2 billion tonnes of plastic are estimated to have been made between 1950 and 2017. More than half this plastic has been produced since 2004. In 2020, 400 million tonnes of plastic were produced. If global trends on plastic demand continue, it is estimated that by 2050 annual global plastic production will reach over 1, ...

Rubber
Rubber, also called India rubber, latex, Amazonian rubber, ''caucho'', or ''caoutchouc'', as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds. Thailand, Malaysia, and Indonesia are three of the leading rubber producers. Types of polyisoprene that are used as natural rubbers are classified as elastomers. Currently, rubber is harvested mainly in the form of the latex from the rubber tree (''Hevea brasiliensis'') or others. The latex is a sticky, milky and white colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called "tapping". The latex then is refined into the rubber that is ready for commercial processing. In major areas, latex is allowed to coagulate in the collection cup. The coagulated lumps are collected and processed into dry forms for sale. Natural rubber is used extensively in many applications and products, either alone or in combination wit ...

Silicone
A silicone or polysiloxane is a polymer made up of siloxane (−R2Si−O−SiR2−, where R = organic group). They are typically colorless oils or rubber-like substances. Silicones are used in sealants, adhesives, lubricants, medicine, cooking utensils, thermal insulation, and electrical insulation. Some common forms include silicone oil, silicone grease, silicone rubber, silicone resin, and silicone caulk. Chemistry More precisely called polymerized siloxanes or polysiloxanes, silicones consist of an inorganic silicon–oxygen backbone chain (⋯−Si−O−Si−O−Si−O−⋯) with two organic groups attached to each silicon center. Commonly, the organic groups are methyl. The materials can be cyclic or polymeric. By varying the −Si−O− chain lengths, side groups, and crosslinking, silicones can be synthesized with a wide variety of properties and compositions. They can vary in consistency from liquid to gel to rubber to hard plastic. The most common siloxan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Relief Valve
A relief valve or pressure relief valve (PRV) is a type of safety valve used to control or limit the pressure in a system; pressure might otherwise build up and create a process upset, instrument or equipment failure, or fire. The pressure is relieved by allowing the pressurized fluid to flow from an auxiliary passage out of the system. The relief valve is designed or set to open at a predetermined set pressure to protect pressure vessels and other equipment from being subjected to pressures that exceed their design limits. When the set pressure is exceeded, the relief valve becomes the "path of least resistance" as the valve is forced open and a portion of the fluid is diverted through the auxiliary route. In systems containing flammable fluids, the diverted fluid (liquid, gas or liquid-gas mixture) is either recaptured by a low pressure, high-flow vapor recovery system or is routed through a piping system known as a ''flare header'' or ''relief header'' to a central, elevated ga ...

Vacuum
A vacuum is a space devoid of matter. The word is derived from the Latin adjective ''vacuus'' for "vacant" or "void". An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure. Physicists often discuss ideal test results that would occur in a ''perfect'' vacuum, which they sometimes simply call "vacuum" or free space, and use the term partial vacuum to refer to an actual imperfect vacuum as one might have in a laboratory or in space. In engineering and applied physics on the other hand, vacuum refers to any space in which the pressure is considerably lower than atmospheric pressure. The Latin term ''in vacuo'' is used to describe an object that is surrounded by a vacuum. The ''quality'' of a partial vacuum refers to how closely it approaches a perfect vacuum. Other things equal, lower gas pressure means higher-quality vacuum. For example, a typical vacuum cleaner produces enough suction to reduce air pressure by around 20%. But hig ...

Hand Pump
Hand pumps are manually operated pumps; they use human power and mechanical advantage to move fluids or air from one place to another. They are widely used in every country in the world for a variety of industrial, marine, irrigation and leisure activities. There are many different types of hand pump available, mainly operating on a piston, diaphragm or rotary vane principle with a check valve on the entry and exit ports to the chamber operating in opposing directions. Most hand pumps are either piston pumps or plunger pumps, and are positive displacement. Hand pumps are commonly used in developing countries for both community supply and self-supply of water and can be installed on boreholes or hand-dug wells. History One sort of pump once common worldwide was a hand-powered water pump, or 'pitcher pump'. It was commonly installed over community water wells in the days before piped water supplies. In parts of Britain and Ireland, it was often called ''the parish pump' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
