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 ...

Clitoris
In amniotes, the clitoris ( or ; : clitorises or clitorides) is a female sex organ. In humans, it is the vulva's most erogenous zone, erogenous area and generally the primary anatomical source of female Human sexuality, sexual pleasure. The clitoris is a complex structure, and its size and sensitivity can vary. The visible portion, the glans, of the clitoris is typically roughly the size and shape of a pea and is estimated to have at least 8,000 Nerve, nerve endings. * * Peters, B; Uloko, M; Isabey, PHow many Nerve Fibers Innervate the Human Clitoris?

Masturbation
Masturbation is a form of autoeroticism in which a person Sexual stimulation, sexually stimulates their own Sex organ, genitals for sexual arousal or other sexual pleasure, usually to the point of orgasm. Stimulation may involve the use of hands, everyday objects, sex toys, or more rarely, the mouth (autofellatio and autocunnilingus). Masturbation may also be performed with a Sexual partner, sex partner, either masturbating together or watching the other partner masturbate and this is known as "mutual masturbation". Masturbation is frequent in both sexes. Various medical and psychological benefits have been attributed to a healthy attitude toward sexual activity in general and to masturbation in particular. No Causality, causal relationship between masturbation and any form of mental or physical disorder has been found. Masturbation is considered by clinicians to be a healthy, normal part of sexual enjoyment. The only exceptions to "masturbation causes no harm" are certain cas ...

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 ...

Human Sexual Response Cycle
The human sexual response cycle is a four-stage model of physiological responses to sexual stimulation, which, in order of their occurrence, are the excitement, plateau, orgasmic, and resolution phases. This physiological response model was first formulated by William H. Masters and Virginia E. Johnson, in their 1966 book ''Human Sexual Response''. Since that time, other models regarding human sexual response have been formulated by several scholars who have criticized certain inaccuracies in the human sexual response cycle model. Excitement phase The excitement phase (also known as the arousal phase or initial excitement phase) is the first stage of the human sexual response cycle, which occurs as a result of physical or mental erotic stimuli, such as kissing, making out, fantasizing or viewing erotic images, that leads to sexual arousal. During this stage, the body prepares for sexual intercourse, initially leading to the plateau phase. There is wide socio-cultural variati ...

Non-penetrative Sex
Non-penetrative sex or outercourse is Human sexual activity, 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 (sexual act), fingering or oral sex. It generally excludes the penetrative aspects of sexual intercourse, vaginal, anal sex, anal, or oral sex, but includes various forms of sexual and non-sexual activity, such as #Frottage, frottage, #Manual sex, manual sex, #Mutual masturbation, mutual masturbation, kissing, or Hug, 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 inter ...

Sexual Stimulation
Sexual stimulation is anything that leads to sexual arousal or orgasm. This thing can be physical or of other senses, and is known as a stimulus. Sexual stimulation is a broad term, usually understood to mean physical touching of the genitals or other body parts. The term can, however, include stimuli affecting the mind ( sexual fantasy), or senses other than touch (such as sight, smell, or hearing). Sufficient physical stimulation of the genitals usually results in an orgasm. Stimulation can be by oneself (masturbation or sexual fantasy) 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 partner controls the level of stimulation to prolong the experience leading up to orgasm. Physical sexual stimulation Physical sexual stimulation consists of touching the genitals or other erogenous zones. Genital Masturbation, ero ...

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 ...

Refractory Period (sex)
In human sexuality, the refractory period is usually the recovery phase after orgasm during which it is physiologically impossible for males to have additional orgasms. This phase begins immediately after ejaculation and lasts until the excitement phase of the human sexual response cycle begins anew with low-level response. It is generally reported that females do not experience a refractory period and can thus experience an additional orgasm (or multiple orgasms) soon after the first one. However, some sources state that both males and females experience a refractory period because women may also experience a moment after orgasm in which further sexual stimulation does not produce excitement. Factors and theories Although the refractory period varies widely among individuals, ranging from minutes to days, most men cannot achieve or maintain an erection during this time, and many perceive a psychological feeling of satisfaction and are temporarily uninterested in further sexual a ...

Nocturnal Emission
A wet dream, sex dream, or sleep orgasm, is a spontaneous occurrence of sexual arousal during sleep that includes ejaculation (nocturnal emission) and orgasm for a male, and vaginal lubrication and/or orgasm for a female. Context Nocturnal emissions can happen after stressful dreams in REM sleep which activate the sympathetic nervous system, hence leading to ejaculation. They can also happen after sex dreams. Nocturnal emissions can start as early as age ten, and are most common during adolescence and early young adult years, but they may happen any time after puberty. Men can wake up during a wet dream, or sleep through it, but for women, some researchers have added the requirement that they should awaken during the orgasm, and perceive that the orgasm happened before it counts as a ''wet dream''. Vaginal lubrication alone does not mean that the woman has had an orgasm. Composition Due to the difficulty in collecting ejaculate produced during nocturnal emissions, relati ...

Vagina
In mammals and other animals, the vagina (: vaginas or vaginae) is the elastic, muscular sex organ, reproductive organ of the female genital tract. In humans, it extends from the vulval vestibule to the cervix (neck of the uterus). The #Vaginal opening and hymen, vaginal introitus is normally partly covered by a thin layer of mucous membrane, mucosal tissue called the hymen. The vagina allows for Copulation (zoology), copulation and birth. It also channels Menstruation (mammal), menstrual flow, which occurs in humans and closely related primates as part of the menstrual cycle. To accommodate smoother penetration of the vagina during sexual intercourse or other sexual activity, vaginal moisture increases during sexual arousal in human females and other female mammals. This increase in moisture provides vaginal lubrication, which reduces friction. The texture of the vaginal walls creates friction for the penis during sexual intercourse and stimulates it toward ejaculation, en ...

Human Sexual Activity
Human sexual activity, human sexual practice or human sexual behaviour is the manner in which humans experience and express Human sexuality, their sexuality. People engage in a variety of sexual acts, ranging from activities done alone (e.g., masturbation) to acts with another person (e.g., sexual intercourse, non-penetrative sex, oral sex, etc.) or persons (e.g., orgy) in varying patterns of frequency, for a wide variety of reasons. Sexual activity usually results in sexual arousal and physiological changes in the aroused person, some of which are pronounced while others are more subtle. Sexual activity may also include conduct and activities which are intended to arouse the sexual interest of another or enhance the sex life of another, such as strategies to find or attract partners (courtship and Display (zoology), display behaviour), or personal interactions between individuals (for instance, foreplay or BDSM). Sexual activity may follow sexual arousal. Human sexual activit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxytocin
Oxytocin is a peptide hormone and neuropeptide normally produced in the hypothalamus and released by the posterior pituitary. Present in animals since early stages of evolution, in humans it plays roles in behavior that include Human bonding, social bonding, love, reproduction, childbirth, and the Postpartum period, period after childbirth. Oxytocin is released into the bloodstream as a hormone in response to Human sexual activity, sexual activity and during childbirth. It is also available in Oxytocin (medication), pharmaceutical form. In either form, oxytocin stimulates uterine contractions to speed up the process of childbirth. In its natural form, it also plays a role in maternal bonding and lactation, milk production. Production and secretion of oxytocin is controlled by a positive feedback mechanism, where its initial release stimulates production and release of further oxytocin. For example, when oxytocin is released during a contraction of the uterus at the start of c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
