Double Penetration Dildo
A double penetration dildo or double dildo is a type of sex toy used for double penetration, the simultaneous entry of two bodily orifices at the same time, belonging to either one or two people. It is a dildo designed in the form of two penetrative stimulators (either penis-shaped or non-phallic) that are either separate or fixed on a single shaft. Some double penetration dildos include a vibrating motor that allows them to be used as double penetration vibrators. Use The following three sexual configurations can be performed using double penetration dildos: *Vagina-to-vagina. Some women use double-ended dildos as part of their sex play with a second woman. The double-ended nature of the dildo allows penetration in two vaginas simultaneously. *Vagina-to-anus. The majority of double-penetration dildos are designed for simultaneous stimulation of anal and vaginal erogenous zones, but in the case of elongated "double-headed" devices it is possible for two partners to use the sa ...

Love Egg
A love egg is a type of egg or bullet shaped vibrator that is used for stimulation. They can also be referred to as egg vibrators or bullet vibrators, depending on their shape. They are typically weaker than larger external vibrators, such as wands, but are still popular due to their lower price and discreet nature. The primary purpose of these vibrators is targeted stimulation of internal or external erogenous zones. History Love eggs have a historical context that can be traced back to the early 1900s when vibrators were initially invented as medical devices for treating female hysteria. In the 1950s, they became more readily available for sexual pleasure, and some were designed for insertion into the vagina or anus. Nonetheless, the contemporary love egg was developed during the 1980s and 1990s when advancements in technology permitted the creation of smaller and more inconspicuous sex toys. Because of their compact size and the possibility of using them discreetly, love ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
G-spot Vibrator
A G-spot vibrator is a sex toy with female and male varieties. The female version of the device is built to massage the G-spot, described as a bean-shaped area of the vagina. Some women report that it is an erogenous zone which, when stimulated, can lead to strong sexual arousal, powerful orgasms and female ejaculation. The male version of the G-spot vibrator is used for massaging the prostate for both sexual and health-related reasons. Female and male versions Female G-spot vibrators The female type is of phallus-like shape and especially designed for stimulating the G-spot. It first appeared as a response to complaints that vaginal penetration alone, provided by the penis or otherwise, was generally not enough for women to reach orgasm. Women usually need direct clitoral stimulation to orgasm, and stimulating the G-spot area through sexual penetration, especially in the missionary position, is difficult to achieve because of the special angle at which penetration must occur.

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.

Anal Vibrator
file:Unisex Superslim Buttplug - Flickr - stnu.jpg, Unisex Superslim Buttplug - Flickr - stnu. {{unsourced, date=June 2018 An anal vibrator is a vibrator (sex toy), vibrator designed for sexual stimulation of the anus of both men and women. All anal vibrators have one common feature: they produce a vibrating effect in the rectum for pleasurable sensations. Anal vibrators differ from other types of vibrators in that they have a flared base to prevent possible loss in the rectum. The average size of an anal vibrator is smaller than vibrators intended for vaginal penetration and may vary from 4-6 inches long and about 1 inch wide. As well as other vibrators designed for external and internal stimulation, anal vibrators are usually battery operated: the batteries may be inside the unit or connected by wire to a power pack. Unlike anal dildos, such as butt plugs, anal probes and anal beads, vibrating anal toys may produce various stimulating effects: rotating, vibrating or pul ...

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, ...

Pyrex
Pyrex (trademarked as ''PYREX'' and ''pyrex'') is a brand introduced by Corning Inc. in 1915 for a line of clear, low-thermal-expansion borosilicate glass used for laboratory glassware and kitchenware. It was later expanded to include kitchenware products made of soda-lime glass and other materials. In 1998, the kitchenware division of Corning Inc. responsible for the development of Pyrex spun off from its parent company as Corning Consumer Products Company, subsequently renamed Corelle Brands (and would later merge with Instant Brands). Corning Inc. no longer manufactures or markets consumer products, only industrial ones. Both trademarks, PYREX (all uppercase) and pyrex (all lowercase, introduced in 1975), were used interchangeably in the marketing of kitchenware products made of both borosilicate and soda lime glass, in addition to related accessories, for several decades. The latter trademark is now used for kitchenware sold in the United States, South America, and Asia. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Borosilicate Glass
Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10−6 K−1 at 20 °C), making them more resistant to thermal shock than any other common glass. Such glass is subjected to less thermal stress and can withstand temperature differentials without fracturing of about . It is commonly used for the construction of reagent bottles and flasks as well as lighting, electronics, and cookware. Borosilicate glass is sold under various trade names, including Borosil, Duran, Pyrex, Glassco, Supertek, Suprax, Simax, Bellco, Marinex (Brazil), BSA 60, BSC 51 (by NIPRO), Heatex, Endural, Schott, Refmex, Kimax, Gemstone Well, and MG (India). Single ended self-starting lamps are insulated with a mica disc and contained in a borosilicate glass gas discharge tube (arc tube) and a metal cap. They include the sodium-vapor lamp tha ...

Glass
Glass is a non-crystalline, often transparent, amorphous solid that has widespread practical, technological, and decorative use in, for example, window panes, tableware, and optics. Glass is most often formed by rapid cooling (quenching) of the molten form; some glasses such as volcanic glass are naturally occurring. The most familiar, and historically the oldest, types of manufactured glass are "silicate glasses" based on the chemical compound silica (silicon dioxide, or quartz), the primary constituent of sand. Soda–lime glass, containing around 70% silica, accounts for around 90% of manufactured glass. The term ''glass'', in popular usage, is often used to refer only to this type of material, although silica-free glasses often have desirable properties for applications in modern communications technology. Some objects, such as drinking glasses and eyeglasses, are so commonly made of silicate-based glass that they are simply called by the name of the material. Despite bei ...

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] |
