The breast is one of two prominences located on the upper ventral region of a primate's torso. Both females and males develop breasts from the same embryological tissues.
The nipple is a raised region of tissue on the surface of the breast from which, in females, milk leaves the breast through the lactiferous ducts to feed an infant. The milk can flow through the nipple passively or it can be ejected by smooth muscle contractions that occur along with the ductal system. The nipple is surrounded by the areola, which is often a darker colour than the surrounding skin. A nipple is often called a teat when referring to non-humans. Nipple or teat can also be used to describe the flexible mouthpiece of a baby bottle. In humans, the nipples of both males and females can be stimulated as part of sexual arousal. In many cultures, human female nipples are sexualized, or "regarded as sex objects and evaluated in terms of their physical characteristics and sexiness."
Nose piercing is the piercing of the skin or cartilage which forms any part of the nose, normally for the purpose of wearing jewelry, called a nose-jewel. Among the different varieties of nose piercings, the nostril piercing is the most common.
An earring is a piece of jewelry attached to the ear via a piercing in the earlobe or another external part of the ear. Earrings have been worn by people in different civilizations and historic periods, often with cultural significance.
An eyebrow piercing is a vertical surface piercing, wherein a twelve to eighteen gauge cannula needle is inserted through the bottom of the eyebrow and exits through the top of the eyebrow to permit insertion of jewellery. Those performing the piercing may use a pennington clamp to better guide the needle through the skin. A curved barbell is the most common jewellery inserted post-piercing.
A nipple piercing is a type of body piercing, centered usually at the base of the nipple. It can be pierced at any angle but is usually done horizontally or, less often, vertically. It is also possible to place multiple piercings on top of one another.
Body piercing jewelry is jewelry manufactured specifically for use in body piercing. The jewelry involved in the art of body piercing comes in a wide variety of shapes and sizes in order to best fit the pierced site. Jewelry may be worn for fashion, cultural tradition, religious beliefs, personal symbolism, and many other reasons.
Toplessness refers to the state in which a woman's breasts, including her areolas and nipples, are exposed, especially in a public place or in a visual medium. The male equivalent is barechestedness, also commonly called shirtlessness.
Barbell style piercing jewelry is composed of a straight bar with a bead on each end, one or both beads unscrewable for removal and/or changing of the beads. Often one of the beads is fixed, either via epoxy or welding, so that only one bead is used to install or remove the jewelry. Barbell threads are usually right-handed.
Pasties are patches that cover a person's nipples and areolae, typically affixed with adhesive. Though they are commonly associated with strippers, burlesque shows and erotic entertainment, they are also, at times, worn as an undergarment, beachwear, or as a form of protest during women's rights events such as Go Topless Day to avoid potential prosecution under indecency laws.
A nipple clamp is a type of sex toy that is applied to a person's nipples to pinch them. Varieties of nipple clamp include clothes-pin-style, tweezer and clover. Nipple clamps are used to cause pain in the nipples as part of certain BDSM activities. They are also used to produce erotic stimulation as part of nipple play. In this context they are not primarily used to produce pain but rather to increase nipple sensation. Their use traps blood in the nipples, increasing the sensitivity of the nipple. The sexologist Carol Queen says that "clamps are also very useful for hands-free nipple play".
An inverted nipple is a condition where the nipple, instead of pointing outward, is retracted into the breast. In some cases, the nipple will be temporarily protruded if stimulated. Both women and men can have inverted nipples.
Labia piercings are one type of female genital piercing. This piercing can be placed either through the labia minora or the labia majora. They are one of the simpler and more common genital piercings performed on women, and are often pierced in symmetrical pairs. Like all genital piercings, depending on jewellery and placement, they may provide additional stimulation to one or both partners during sexual intercourse.
A nipple shield is a nipple-shaped sheath worn over the areola and nipple during breastfeeding. Modern nipple shields are made of soft, thin, flexible silicone and have holes at the end of the nipple section to allow the breast milk to pass through.
Mastopexy is the plastic surgery mammoplasty procedure for raising sagging breasts upon the chest of the woman, by changing and modifying the size, contour, and elevation of the breasts. In a breast-lift surgery to re-establish an aesthetically proportionate bust for the woman, the critical corrective consideration is the tissue viability of the nipple-areola complex (NAC), to ensure the functional sensitivity of the breasts for lactation and breast-feeding.
Genital jewellery, also known as sex jewellery and adult jewellery, is jewellery which is designed specifically for wear on or to accentuate the genitals. In a wider sense also nipple rings and some butt-plugs may be called genital jewellery.
Ptosis or sagging of the female breast is a natural consequence of aging. The rate at which a woman's breasts drop and the degree of ptosis depends on many factors. The key factors influencing breast ptosis over a woman's lifetime are cigarette smoking, her number of pregnancies, higher body mass index, larger bra cup size, and significant weight change. Post-menopausal women or people with collagen deficiencies may experience increased ptosis due to a loss of skin elasticity. Many women and medical professionals mistakenly believe that breastfeeding increases sagging. It is also commonly believed that the breast itself offers insufficient support and that wearing a bra prevents sagging, which has not been found to be true.
A plug, in the context of body modification, is a short, cylindrical piece of jewelry commonly worn in larger-gauge body piercings. Modern western plugs are also called flesh tunnels. Because of their size—which is often substantially thicker than a standard metal earring—plugs can be made out of almost any material. Acrylic glass, metal, wood, bone, stone, horn, glass, silicone or porcelain are all potential plug materials.
Body piercing, which is a form of body modification, is the practice of puncturing or cutting a part of the human body, creating an opening in which jewelry may be worn, or where an implant could be inserted. The word piercing can refer to the act or practice of body piercing, or to an opening in the body created by this act or practice. It can also, by metonymy, refer to the resulting decoration, or to the decorative jewelry used. Piercing implants alter body and/or skin profile and appearance. Although the history of body piercing is obscured by popular misinformation and by a lack of scholarly reference, ample evidence exists to document that it has been practiced in various forms by multiple sexes since ancient times throughout the world.
