Gay Sexual Practices
Sexual activities involving men who have sex with men (MSM), regardless of their sexual orientation, 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. Many MSM, however, do not engage in anal sex, and may engage in oral sex, frottage or frot, and/or mutual masturbation instead. Among men who have anal sex with other men, the partner who inserts his penis 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 using a condom, this is referred to as bareback sex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mutual Masturbation
Non-penetrative sex or outercourse is sexual activity that usually does not include sexual penetration, but some forms, particularly when termed ''outercourse'', include penetrative aspects, that may result from forms of fingering or oral sex. It generally excludes the penetrative aspects of vaginal, anal, or oral sex, but includes various forms of sexual and non-sexual activity, such as frottage, manual sex, mutual masturbation, kissing, or hugging.Se272 anpage 301 for two different definitions of outercourse (first of the pages for no-penetration definition; second of the pages for no-penile-penetration definition). People engage in non-penetrative sex for a variety of reasons, including as a form of foreplay or as a primary or preferred sexual act.Sehere onwards anpages 47–49 for views on what constitutes virginity loss and therefore sexual intercourse or other sexual activity; source discusses how gay and lesbian individuals define virginity loss, and how the maj ...

Prostate
The prostate is an male accessory gland, accessory gland of the male reproductive system and a muscle-driven mechanical switch between urination and ejaculation. It is found in all male mammals. It differs between species anatomically, chemically, and physiologically. Anatomically, the prostate is found below the 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 produces and contains 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 Alkalinity, 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 first part of ej ...

Orgasm
Orgasm (from Greek , ; "excitement, swelling"), sexual climax, or simply climax, is the sudden release of accumulated sexual excitement during the sexual response cycle, characterized by intense sexual pleasure resulting in rhythmic, involuntary muscular contractions in the pelvic region.Se133–135 for orgasm information, anpage 76 for G-spot and vaginal nerve ending information. Orgasms are controlled by the involuntary or autonomic nervous system and are experienced by both males and females; the body's response includes muscular spasms (in multiple areas), a general euphoric sensation, and, frequently, body movements and vocalizations. The period after orgasm (known as the resolution phase) is typically a relaxing experience after 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 accompanied by ejaculation) and of ...

Human Anus
In humans, the anus (: anuses or ani; from Latin ''ānus'', "ring", "circle") is the external opening of the rectum located inside the intergluteal cleft. Two sphincters control the exit of Human feces, 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 relax as required by normal physiological functioning. The inner sphincter is involuntary and the outer is voluntary. Above the anus is the perineum, which is also located beneath the vulva 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 Human sexuality, sexuality. Attitudes toward anal sex vary, and it is illeg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nerve
A nerve is an enclosed, cable-like bundle of nerve fibers (called axons). Nerves have historically been considered the basic units of the peripheral nervous system. A nerve provides a common pathway for the Electrochemistry, 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 is an extension of an individual neuron, along with other supportive cells such as some Schwann cells that coat the axons in myelin. Each axon is surrounded by a layer of connective tissue called the endoneurium. The axons are bundled together into groups called Nerve fascicle, fascicles, and each fascicle is wrapped in a layer of connective tissue called the perineurium. The entire nerve is wrapped in a layer of connective tissue called the epineurium. Nerve cells (often called neurons) are further classified as either Sensory neuron, sens ...

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 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 then in context to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Versatile (sex)
In human sexuality, top, bottom, and versatile are roles during sexual activity, especially between two (or more) males. A ''top'' is usually a person who penetrates, a ''bottom'' is usually one who receives penetration, and someone who is ''versatile'' engages in either or both roles. These terms may be elements of self-identity that indicate an individual's usual preference and habits, but might also describe broader sexual identities and social roles. The terms ''top'' and ''bottom'' do not refer to the literal physical position during sex. For men who have sex with men and do not engage in anal sex, the term "side" has been proposed and has seen commercial use. Side men do not engage in anal sex but rather enjoy outercourse. Top A top is usually a person who engages in the penetrative role during sexual activity; for men who have sex with men (MSM), this often involves penetration using the penis during anal or oral sex. ''Top'' is also used as a verb meaning "to penetra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Together with the testes and surrounding structures, the penis functions as part of the male reproductive system. The main parts of the penis are the Root of penis, root, Body of penis, body, the epithelium of the penis, including the shaft skin, and the foreskin covering the glans penis, glans. The body of the penis is made up of three columns of tissue (biology), tissue: two Corpus cavernosum penis, corpora cavernosa on the dorsal side and corpus spongiosum penis, corpus spongiosum between them on the ventral side.
