Mammary intercourse is a sex act, performed as either foreplay or as non-penetrative sex, that involves the stimulation of a man's penis by a woman's breasts and vice versa.Alex Comfort, ''The Joy of Sex'' (1972) p. 67-9 It involves placing the penis between a woman's breasts and moving the penis up and down to simulate sexual penetration and to create sexual pleasure. It may be used as an alternative to a handjob. Practice Mammary intercourse involves a man kneeling or sitting on a woman's stomach or chest, placing his erect penis on her cleavage, and rubbing or thrusting while the breasts are squeezed around the penile shaft, by either the woman or the man, creating tightness similar to masturbation, and in simulation of penetrative sex. A lubricant, masturbation cream, or saliva may be used between the breasts or on the penis. Alternatively, the woman can tighten her breasts around the penis and move them back and forth. Other positions involves either the man standing whi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Erotic Stimulation
Sexual stimulation is any 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 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 fantasizing). Sufficient stimulation of the 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 sexual activity), by use of objects or tools, or by some combination of these methods. Some people practice orgasm control, whereby a person or their sexual partner controls the level of sexual stimulation to delay orgasm, and to prolong the sexual experience leading up to orgasm.

Sexual Intercourse
Sexual intercourse (or coitus or copulation) is a sexual activity typically involving the insertion and thrusting of the penis into the vagina for sexual pleasure or reproduction.Sexual intercourse most commonly means penile–vaginal penetration for sexual pleasure or sexual reproduction; dictionary sources state that it especially means this, and scholarly sources over the years agree. See, for example; * * * * * * * * * This is also known as vaginal intercourse or vaginal sex. Other forms of penetrative sexual intercourse include anal sex (penetration of the anus by the penis), oral sex (penetration of the mouth by the penis or oral penetration of the female genitalia), fingering (sexual penetration by the fingers) and penetration by use of a dildo (especially a strap-on dildo). These activities involve physical intimacy between two or more individuals and are usually used among humans solely for physical or emotional pleasure and can contribute to human bonding. Ther ...

Safe Sex
Safe sex is sexual activity using methods or contraceptive devices (such as condoms) to reduce the risk of transmitting or acquiring sexually transmitted infections (STIs), especially HIV. "Safe sex" is also sometimes referred to as safer sex or protected sex to indicate that some safe sex practices do not eliminate STI risks. It is also sometimes used colloquially to describe methods aimed at preventing pregnancy that may or may not also lower STI risks. The concept of "safe sex" emerged in the 1980s as a response to the global AIDS epidemic, and possibly more specifically to the AIDS crisis in the United States. Promoting safe sex is now one of the main aims of sex education and STI prevention, especially reducing new HIV infections. Safe sex is regarded as a harm reduction strategy aimed at reducing the risk of STI transmission. Although some safe sex practices (like condoms) can also be used as birth control (''contraception''), most forms of contraception do not prot ...

Sex Worker
A sex worker is a person who provides sex work, either on a regular or occasional basis. The term is used in reference to those who work in all areas of the sex industry.Oxford English Dictionary, "sex worker" According to one view, sex work is different from sexual exploitation, or the forcing of a person to commit sexual acts, in that sex work is voluntary "and is seen as the commercial exchange of sex for money or goods". In an attempt to further clarify the broad term "sex work", John E. Exner, an American psychologist, worked with his colleagues to create five distinct classes for categorizing sex workers. One scholarly article details the classes as follows: "specifically, the authors articulated Class I, or the upper class (courtesans) of the profession, consisting of call girls; Class II was referred to as the middle class, consisting of 'in-house girls' who typically work in an establishment on a commission basis; Class III, the lower middle class, were 'streetwalkers' who ...

Condom
A condom is a sheath-shaped barrier device used during sexual intercourse to reduce the probability of pregnancy or a sexually transmitted infection (STI). There are both male and female condoms. With proper use—and use at every act of intercourse—women whose partners use male condoms experience a 2% per-year pregnancy rate. With typical use the rate of pregnancy is 18% per-year. Their use greatly decreases the risk of gonorrhea, chlamydia, trichomoniasis, hepatitis B, and HIV/AIDS. To a lesser extent, they also protect against genital herpes, human papillomavirus (HPV), and syphilis. The male condom is rolled onto an erect penis before intercourse and works by forming a physical barrier which blocks semen from entering the body of a sexual partner. Male condoms are typically made from latex and, less commonly, from polyurethane, polyisoprene, or lamb intestine. Male condoms have the advantages of ease of use, ease of access, and few side effects. Individuals with late ...

Semen
Semen, also known as seminal fluid, is an organic bodily fluid created to contain spermatozoa. It is secreted by the gonads (sexual glands) and other sexual organs of male or hermaphroditic animals and can fertilize the female ovum. Semen is produced and originates from the seminal vesicle, which is located in the pelvis. The process that results in the discharge of semen from the urethral orifice is called ejaculation. In humans, seminal fluid contains several components besides spermatozoa: proteolytic and other enzymes as well as fructose are elements of seminal fluid which promote the survival of spermatozoa, and provide a medium through which they can move or "swim". The fluid is designed to be discharged deep into the vagina, so the spermatozoa can pass into the uterus and form a zygote with an egg. Semen is also a form of genetic material. In animals, semen has been collected for cryoconservation. Cryoconservation of animal genetic resources is a practice that call ...

Pre-ejaculate
Pre-ejaculate (also known as pre-ejaculatory fluid, pre-seminal fluid or Cowper's fluid, and colloquially as ''pre-cum'') is a clear, colorless, viscous fluid that is emitted from the urethra of the penis during sexual arousal. It is similar in composition to semen but has distinct chemical differences. The presence of sperm in the fluid is variable from low to absent. Pre-ejaculate functions as a lubricant and an acid neutralizer. Origin and composition The fluid is discharged from the urethra of the penis during arousal, masturbation, foreplay or at an early stage during sexual intercourse, some time before the individual fully reaches orgasm and semen is ejaculated. It is primarily produced by the bulbourethral glands ( Cowper's glands), with the glands of Littré (the mucus-secreting urethral glands) also contributing. The amount of fluid that is issued varies widely among individuals. Some individuals do not produce any pre-ejaculate fluid, while others emit as much as . The ...

Mucous Membranes
A mucous membrane or mucosa is a membrane that lines various cavities in the body of an organism and covers the surface of internal organs. It consists of one or more layers of epithelial cells overlying a layer of loose connective tissue. It is mostly of endodermal origin and is continuous with the skin at body openings such as the eyes, eyelids, ears, inside the nose, inside the mouth, lips, the genital areas, the urethral opening and the anus. Some mucous membranes secrete mucus, a thick protective fluid. The function of the membrane is to stop pathogens and dirt from entering the body and to prevent bodily tissues from becoming dehydrated. Structure The mucosa is composed of one or more layers of epithelial cells that secrete mucus, and an underlying lamina propria of loose connective tissue. The type of cells and type of mucus secreted vary from organ to organ and each can differ along a given tract. Mucous membranes line the digestive, respiratory and reproductive tract ...

Sexually Transmitted Infection
Sexually transmitted infections (STIs), also referred to as sexually transmitted diseases (STDs) and the older term venereal diseases, are infections that are Transmission (medicine), spread by Human sexual activity, sexual activity, especially Sexual intercourse, vaginal intercourse, anal sex, and oral sex. STIs often do not initially cause symptoms, which results in a risk of passing the infection on to others. Symptoms and signs of STIs may include vaginal discharge, penile discharge, genital ulcers, ulcers on or around the genitals, and pelvic pain. Some STIs can cause infertility. Bacterial STIs include Chlamydia infection, chlamydia, gonorrhea, and syphilis. Viral STIs include genital herpes, HIV/AIDS, and genital warts. Parasitic STIs include trichomoniasis. STI diagnostic tests are usually easily available in the developed world, but they are often unavailable in the developing world. Some vaccinations may also decrease the risk of certain infections including Hepa ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Fingering (sex Act)
Fingering is typically the use of fingers or hands to sexually stimulate the vulva (including the clitoris) or vagina. Vaginal fingering is legally and medically called digital penetration or digital penetration of the vagina. Fingering may also include the use of fingers to sexually stimulate the anus. Fingering may be performed on oneself (masturbation) or by or with a sexual partner. When performed on the vulva or vagina by a sexual partner, it is a form of mutual masturbation, and is analogous to a handjob (the manual stimulation of the penis). It may be used for sexual arousal or foreplay, constitute an entire sexual encounter, or be used as a form of non-penetrative sexual activity. Stimulation Vulva Parts of the vulva, especially the clitoris, are erogenous zones. * Massage of the vulva, and in particular the clitoris, is the most common way for a woman to achieve an orgasm. Studies indicate that 70-80% of women require direct clitoral stimulation to achieve orgasm. ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
