Gay Sexual Practices
Gay sexual practices are sexual activities involving men who have sex with men (MSM), regardless of their sexual orientation or sexual identity. These practices can include anal sex, non-penetrative sex, and oral sex. Evidence shows that sex between men is significantly underreported in surveys. Behaviors Various sex positions may be performed during sexual activity between men. Evidence shows that sex between men is significantly underreported in surveys due to social desirability bias. Anal sex Historically, anal sex has been popularly associated with male homosexuality and MSM. Many MSM, however, do not engage in anal sex, and may engage in oral sex, frottage or frot, or mutual masturbation instead. Among men who have anal sex with other men, the insertive partner may be referred to as the ''top'', the one being penetrated may be referred to as the ''bottom'', and those who enjoy either role may be referred to as '' versatile''. When MSM engage in anal sex without usin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bisexuality
Bisexuality is a romantic or sexual attraction or behavior toward both males and females, or to more than one gender. It may also be defined to include romantic or sexual attraction to people regardless of their sex or gender identity, which is also known as '' pansexuality.'' The term ''bisexuality'' is mainly used in the context of human attraction to denote romantic or sexual feelings toward both men and women, and the concept is one of the three main classifications of sexual orientation along with heterosexuality and homosexuality, all of which exist on the heterosexual–homosexual continuum. A bisexual identity does not necessarily equate to equal sexual attraction to both sexes; commonly, people who have a distinct but not exclusive sexual preference for one sex over the other also identify themselves as bisexual. Scientists do not know the exact cause of sexual orientation, but they theorize that it is caused by a complex interplay of genetic, hormonal, and envi ...

National Survey Of Sexual Health And Behavior
The National Survey of Sexual Health and Behavior is a decade-long nationally representative study of human sexual behavior. The research has been conducted in the United States by researchers from the Center for Sexual Health Promotion in the School of Public Health at Indiana University in Bloomington. ''Time'' magazine called the NSSHB "the most comprehensive survey of its kind in nearly two decades and the first to include teenagers." Former U.S. Surgeon General Dr. Joycelyn Elders has written the following about NSSHB findings: "These data are important for keeping the nation moving forward in the area of sexual health and well being. In the absence of scientific data available to construct an accurate and up-to-date view, opinions in the field of sexual science can vary widely from person to person." There have been a total of seven waves of the NSSHB, all conducted between 2009 and 2018. More than 30 scientific articles have been published from these data. Articles based on ...

Prostate
The prostate is both an Male accessory gland, accessory gland of the male reproductive system and a muscle-driven mechanical switch between urination and ejaculation. It is found only in some mammals. It differs between species anatomically, chemically, and physiologically. Anatomically, the prostate is found below the Urinary bladder, bladder, with the urethra passing through it. It is described in gross anatomy as consisting of lobes and in microanatomy by zone. It is surrounded by an elastic, fibromuscular capsule and contains glandular tissue as well as connective tissue. The prostate glands produce and contain fluid that forms part of semen, the substance emitted during ejaculation as part of the male Human sexual response cycle, sexual response. This prostatic fluid is slightly alkaline, milky or white in appearance. The alkalinity of semen helps neutralize the acidity of the vagina, vaginal tract, prolonging the lifespan of sperm. The prostatic fluid is expelled in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Human Anus
In humans, the anus (from Latin '' anus'' meaning "ring", "circle") is the external opening of the rectum, located inside the intergluteal cleft and separated from the genitals by the perineum. Two sphincters control the exit of feces from the body during an act of defecation, which is the primary function of the anus. These are the internal anal sphincter and the external anal sphincter, which are circular muscles that normally maintain constriction of the orifice and which relaxes as required by normal physiological functioning. The inner sphincter is involuntary and the outer is voluntary. It is located behind the perineum which is located behind the vagina or scrotum. In part owing to its exposure to feces, a number of medical conditions may affect the anus such as hemorrhoids. The anus is the site of potential infections and other conditions, including cancer (see Anal cancer). With anal sex, the anus can play a role in sexuality. Attitudes toward anal sex vary, an ...

Nerve
A nerve is an enclosed, cable-like bundle of nerve fibers (called axons) in the peripheral nervous system. A nerve transmits electrical impulses. It is the basic unit of the peripheral nervous system. A nerve provides a common pathway for the electrochemical nerve impulses called action potentials that are transmitted along each of the axons to peripheral organs or, in the case of sensory nerves, from the periphery back to the central nervous system. Each axon, within the nerve, is an extension of an individual neuron, along with other supportive cells such as some Schwann cells that coat the axons in myelin. Within a nerve, each axon is surrounded by a layer of connective tissue called the endoneurium. The axons are bundled together into groups called fascicles, and each fascicle is wrapped in a layer of connective tissue called the perineurium. Finally, the entire nerve is wrapped in a layer of connective tissue called the epineurium. Nerve cells (often called neurons) are f ...

Bareback (sexual Act)
Bareback sex is physical sexual activity, especially sexual penetration, without the use of a condom. The topic primarily concerns anal sex between men who have sex with men without the use of a condom, and may be distinguished from unprotected sex because ''bareback sex'' denotes the deliberate act of forgoing condom use. Etymology An LGBT slang term, ''bareback sex'' comes from the equestrian term ''bareback'', which is the practice of riding a horse without a saddle. It is not known when the term (as sexual slang) was first used, although its use did gain momentum in the 1960s with the first appearance in print (as analogous reference) occurring in 1968. The term was used by G.I.s during the Vietnam War when sex without the use of a condom was known as "going in" or "riding" bareback. The term was included in the 1972 publication, ''Playboy's Book of Forbidden Words: A Liberated Dictionary of Improper English''. The term appeared occasionally in print until the 1980s and the ...
