Chemsex
Party and play (PnP), also known as chemsex or wired play, refers to the practice of consuming drugs to enhance sexual activity. This sexual subculture involves recreational drug users engaging in high-risk sexual behaviors under the influence of drugs, often within specific sub-groups. Activities may include unprotected sex with multiple partners during sessions over extended periods, sometimes lasting days. The drug of choice is typically methamphetamine, commonly referred to as ''crystal meth'', ''tina'', or ''T''. Other substances like mephedrone, GHB, GBL, ketamine, and alkyl nitrites (known as poppers) are also used. The term slamsex is used for injection drug users. Studies indicate that individuals participating in such activities have a higher likelihood of acquiring sexually transmitted infections, including HIV/AIDS, due to unprotected sex with numerous partners. Consequently, addressing this issue is considered a significant public health priority. Terminology Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gay Men
Gay men are male homosexuals. Some bisexual men, bisexual and homoromantic men may dually identify as ''gay'' and a number of gay men also identify as ''queer''. Historic terminology for gay men has included ''Sexual inversion (sexology), inverts'' and ''Uranian (sexology), uranians''. Gay men continue to face significant Discrimination against gay men, discrimination in LGBT rights by country or territory, large parts of the world, particularly in most of LGBT rights in Asia, Asia and LGBT rights in Africa, Africa. In the LGBT rights in the United States, United States and the western world, many gay men still experience discrimination in their daily lives, though some openly gay men have reached national success and prominence, including Apple Inc., Apple CEO Tim Cook and heads of state or government such as Edgars Rinkēvičs (president of Latvia since 2023). The word ''gay'' is recommended by LGBTQ groups and style guides to describe all people exclusively attracted to m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anal Intercourse
Anal sex or anal intercourse principally means the insertion and thrusting of the erect penis into a person's anus, or anus and rectum, for sexual pleasure.Sepages 270–271for anal sex information, anpage 118for information about the clitoris. Other forms of anal sex include anal fingering, the use of sex toys, anilingus, and pegging. Although ''anal sex'' most commonly means penileanal penetration, sources sometimes use ''anal intercourse'' to exclusively denote penileanal penetration, and ''anal sex'' to denote any form of anal sexual activity, especially between pairings as opposed to anal masturbation. While anal sex is commonly associated with male homosexuality, research shows that not all homosexual men engage in anal sex and that it is not uncommon in heterosexual relationships. Types of anal sex can also be part of lesbian sexual practices. People may experience pleasure from anal sex by stimulation of the anal nerve endings, and orgasm may be achieved throug ...

Dissociation (psychology)
Dissociation is a concept which concerns a wide array of experiences, ranging from a mild emotional detachment from the immediate surroundings, to a more severe disconnection from physical and emotional experiences. The major characteristic of all dissociative phenomena involves a detachment from reality, rather than a false perception of reality as in psychosis. The phenomena are diagnosable under the ''DSM-5'' as a group of disorders as well as a symptom of other disorders through various diagnostic tools. Its cause is believed to be related to neurobiological mechanisms, trauma, anxiety, and psychoactive drugs. Research has further related it to suggestibility and hypnosis. History French philosopher and psychologist Pierre Janet (1859–1947) is considered to be the author of the concept of dissociation. Unlike some conceptions of dissociation, Janet did not believe that dissociation was a psychological defense. Janet claimed that dissociation occurred only in person ...

Perception
Perception () is the organization, identification, and interpretation of sensory information in order to represent and understand the presented information or environment. All perception involves signals that go through the nervous system, which in turn result from physical or chemical stimulation of the sensory system.Goldstein (2009) pp. 5–7 Vision involves light striking the retina of the eye; smell is mediated by odor molecules; and hearing involves pressure waves. Perception is not only the passive receipt of these signals, but it is also shaped by the recipient's learning, memory, expectation, and attention. Gregory, Richard. "Perception" in Gregory, Zangwill (1987) pp. 598–601. Sensory input is a process that transforms this low-level information to higher-level information (e.g., extracts shapes for object recognition). The following process connects a person's concepts and expectations (or knowledge) with restorative and selective mechanisms, ...

Dissociative Anesthetic
Dissociatives, colloquially dissos, are a subclass of hallucinogens that distort perception of sight and sound and produce feelings of detachment – dissociation – from the environment and/or self. Although many kinds of drugs are capable of such an effect, dissociatives are unique in that they do so in such a way that they produce hallucinogenic effects, which may include dissociation, a general decrease in sensory experience, hallucinations, dream-like states or anesthesia. Despite most dissociatives' main mechanism of action being tied to NMDA receptor antagonism, some of these substances, which are nonselective in action and affect the dopamine and/or opioid systems, may be capable of inducing more ''direct'' and repeatable euphoria or symptoms which are more akin to the effects of typical "hard drugs" or common drugs of abuse. This is likely why dissociatives are considered to be addictive with a fair to moderate potential for abuse, unlike psychedelics. Despite some ...

Hypersomnia
Hypersomnia is a neurological disorder of excessive time spent sleeping or excessive sleepiness. It can have many possible causes (such as seasonal affective disorder) and can cause distress and problems with functioning. In the fifth edition of the ''Diagnostic and Statistical Manual of Mental Disorders'' (DSM-5), hypersomnolence, of which there are several subtypes, appears under sleep-wake disorders. Hypersomnia is a pathological state characterized by a lack of alertness during the waking episodes of the day.American Academy of Sleep Medicine. The international classification of sleep disorders: diagnostic & coding manual (2nd ed). Westchester, IL: American Academy of Sleep Medicine, 2005. It is not to be confused with fatigue, which is a normal physiological state. Daytime sleepiness appears most commonly during situations where little interaction is needed. Since hypersomnia impairs patients' attention levels (wakefulness), quality of life may be impacted as well.Morge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ejaculation
Ejaculation is the discharge of semen (the ''ejaculate''; normally containing sperm) from the penis through the urethra. It is the final stage and natural objective of male sexual stimulation, and an essential component of natural conception. After forming an erection, many men emit Pre-ejaculate, pre-ejaculatory fluid during stimulation prior to ejaculating. Ejaculation involves involuntary Muscle contraction, contractions of the pelvic floor and is normally linked with orgasm. It is a normal part of male Puberty, human sexual development. Ejaculation can occur spontaneously during sleep (a nocturnal emission or "wet dream") or in rare cases because of prostate, prostatic disease. ''Anejaculation'' is the condition of being unable to ejaculate. ''Painful ejaculation, Dysejaculation'' is an ejaculation that is painful or uncomfortable. Retrograde ejaculation is the backward flow of semen from the urethra into the urinary bladder, bladder. Premature ejaculation happens shortly ...

Sexual Arousal
Sexual arousal (also known as sexual excitement) describes the Physiology, physiological and psychological responses in preparation for sexual intercourse or when exposed to Sexual stimulation, sexual stimuli. A number of physiological responses occur in the body and mind as preparation for sexual intercourse, and continue during intercourse. #Male physiological response, Male arousal will lead to an erection, and in #Female physiological response, female arousal, the body's response is engorged sexual tissues such as Erection of nipples, nipples, Clitoral erection, clitoris, Vagina#Microanatomy, vaginal walls, and vaginal lubrication. Stimulus (psychology), Mental stimuli and Stimulus (physiology), physical stimuli such as touch, and the internal fluctuation of hormones, can influence sexual arousal. Sexual arousal has several stages and may not lead to any actual sexual activity beyond a mental arousal and the physiological changes that accompany it. Given sufficient sexual st ...

Sleep
Sleep is a state of reduced mental and physical activity in which consciousness is altered and certain Sensory nervous system, sensory activity is inhibited. During sleep, there is a marked decrease in muscle activity and interactions with the surrounding environment. While sleep differs from wakefulness in terms of the ability to react to Stimulus (physiology), stimuli, it still involves active Human brain, brain patterns, making it more reactive than a coma or disorders of consciousness. Sleep occurs in sleep cycle, repeating periods, during which the body alternates between two distinct modes: rapid eye movement sleep (REM) and Non-rapid eye movement sleep, non-REM sleep. Although REM stands for "rapid eye movement", this mode of sleep has many other aspects, including virtual Rapid eye movement sleep#Muscle, paralysis of the body. Dreams are a succession of images, ideas, emotions, and sensations that usually occur involuntarily in the mind during certain stages of sleep. ...

Stimulant
Stimulants (also known as central nervous system stimulants, or psychostimulants, or colloquially as uppers) are a class of drugs that increase alertness. They are used for various purposes, such as enhancing attention, motivation, cognition, Mood disorder, mood, and physical activity, physical performance. Some stimulants occur naturally, while others are exclusively synthetic. Common stimulants include caffeine, nicotine, amphetamines, cocaine, methylphenidate, and modafinil. Stimulants may be subject to varying forms of regulation, or outright prohibition, depending on jurisdiction. Stimulants increase activity in the sympathetic nervous system, either directly or indirectly. Prototypical stimulants increase synaptic concentrations of neurotransmitter, excitatory neurotransmitters, particularly norepinephrine and dopamine (e.g., methylphenidate). Other stimulants work by binding to the Receptor (biochemistry), receptors of excitatory neurotransmitters (e.g., nicotine) or by ...

Euphoriant
Euphoria ( ) is the experience (or affect) of pleasure or excitement and intense feelings of well-being and happiness. Certain natural rewards and social activities, such as aerobic exercise, laughter, listening to or making music and dancing, can induce a state of euphoria. Euphoria is also a symptom of certain neurological or neuropsychiatric disorders, such as mania. Romantic love and components of the human sexual response cycle are also associated with the induction of euphoria. Certain drugs, many of which are addictive, can cause euphoria, which at least partially motivates their recreational use. Hedonic hotspots – i.e., the pleasure centers of the brain – are functionally linked. Activation of one hotspot results in the recruitment of the others. Inhibition of one hotspot results in the blunting of the effects of activating another hotspot. Therefore, the simultaneous activation of every hedonic hotspot within the reward system is believed to be neces ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
