Sexual arousal

Sexual arousal (also sexual excitement) is typically the arousal of sexual desire during or in anticipation of sexual activity.

Sexual activity usually results in sexual arousal and physiological changes in the aroused person, some of which are pronounced while others are more subtle.

Given sufficient sexual stimulation, sexual arousal in humans reaches its climax during an orgasm.

Sexual stimulation is any stimulus (including bodily contact) that leads to, enhances and maintains sexual arousal, and may lead to orgasm.

Male arousal will lead to an erection, and in female arousal the body's response is engorged sexual tissues such as nipples, vulva, clitoris, vaginal walls and vaginal lubrication. In a woman, sexual arousal leads to increased blood flow to the clitoris and vulva, as well as vaginal transudation - the seeping of moisture through the vaginal walls which serves as lubrication.

Blood and nerve supply to the vulva contribute to the stages of sexual arousal that are helpful in the reproduction process.

Male arousal will lead to an erection, and in female arousal the body's response is engorged sexual tissues such as nipples, vulva, clitoris, vaginal walls and vaginal lubrication.

Clitoral erection is the result of a complex interaction of psychological, neural, vascular and endocrine factors, and is usually, though not exclusively, associated with sexual arousal.

Male arousal will lead to an erection, and in female arousal the body's response is engorged sexual tissues such as nipples, vulva, clitoris, vaginal walls and vaginal lubrication. In a woman, sexual arousal leads to increased blood flow to the clitoris and vulva, as well as vaginal transudation - the seeping of moisture through the vaginal walls which serves as lubrication.

Vaginal lubrication is always present, but production increases significantly near ovulation and during sexual arousal in anticipation of sexual intercourse.

The physical stimulation of an erogenous zone or acts of foreplay can result in arousal, especially if it is accompanied with the anticipation of imminent sexual activity.

An erogenous zone (from Greek ἔρως, érōs "love" and English -genous "producing" from Greek -γενής, -genḗs "born") is an area of the human body that has heightened sensitivity, the stimulation of which may generate a sexual response, such as relaxation, the production of sexual fantasies, sexual arousal and orgasm.

Given the right context, these may lead to the person desiring physical contact, including kissing, cuddling, and petting of an erogenous zone.

Depending on the culture and context, a kiss can express sentiments of love, passion, romance, sexual attraction, sexual activity, sexual arousal, affection, respect, greeting, friendship, peace, and good luck, among many others.

A number of physiological responses occur in the body and mind as preparation for sexual intercourse and continue during it.

Foreplay may precede some sexual activities, often leading to sexual arousal of the partners and resulting in the erection of the penis or natural lubrication of the vagina.

The physical stimulation of an erogenous zone or acts of foreplay can result in arousal, especially if it is accompanied with the anticipation of imminent sexual activity.

Foreplay is a set of emotionally and physically intimate acts between two or more people meant to create sexual arousal and desire for sexual activity.

For example, many people may find nudity, erotica or pornography sexually arousing.

Pornography (often abbreviated porn) is the portrayal of sexual subject matter for the exclusive purpose of sexual arousal.

When sexual arousal is achieved by or dependent on the use of objects, it is referred to as sexual fetishism, or in some instances a paraphilia.

Paraphilia (previously known as sexual perversion and sexual deviation) is the experience of intense sexual arousal to atypical objects, situations, fantasies, behaviors, or individuals.

Given sufficient sexual stimulation, sexual arousal in humans reaches its climax during an orgasm.

Although sexual function and sexuality after spinal cord injury is very often impacted, this injury does not deprive one of sexual feelings such as sexual arousal and erotic desires.

When sexual arousal is achieved by or dependent on the use of objects, it is referred to as sexual fetishism, or in some instances a paraphilia.

Sexual arousal from a particular body part can be further classified as partialism.

For example, many people may find nudity, erotica or pornography sexually arousing.

Erotica is any literary or artistic work that deals substantively with subject matter that is erotically stimulating or sexually arousing but is not pornographic.

On the other hand, a person may be hypersexual, which is a desire to engage in sexual activities considered abnormally high in relation to normal development or culture, or suffering from a persistent genital arousal disorder, which is a spontaneous, persistent, and uncontrollable arousal, and the physiological changes associated with arousal.

Persistent genital arousal disorder (PGAD), previously called persistent sexual arousal syndrome, is spontaneous, persistent, unwanted and uncontrollable genital arousal in the absence of sexual stimulation or sexual desire, and is typically not relieved by orgasm.

However, when a person fails to be aroused in a situation that would normally produce arousal and the lack of arousal is persistent, it may be due to a sexual arousal disorder or hypoactive sexual desire disorder.

Sexual arousal disorder is characterized by a lack or absence of sexual fantasies and desire for sexual activity in a situation that would normally produce sexual arousal, or the inability to attain or maintain typical responses to sexual arousal.

Sexual arousal for a man is usually indicated by the swelling and erection of the penis when blood fills the corpus cavernosum.

An erection is the stiffening and rising of the penis, which occurs during sexual arousal.

Sexual arousal (also sexual excitement) is typically the arousal of sexual desire during or in anticipation of sexual activity.

However, this definition has been met with some disagreement in recent years as it places too much emphasis on Sexual Fantasy which are usually used to supplement sexual arousal.

Male arousal will lead to an erection, and in female arousal the body's response is engorged sexual tissues such as nipples, vulva, clitoris, vaginal walls and vaginal lubrication.

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.

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.

Sexual arousal for a man is usually indicated by the swelling and erection of the penis when blood fills the corpus cavernosum.

Tumescence usually refers to the normal engorgement with blood (vascular congestion) of the erectile tissues, marking sexual excitation, and possible readiness for sexual activity.

Equally, if sexual stimulation stops before orgasm, the physical effects of the stimulation, including the vasocongestion, will subside in a short time.

Typical causes of vasocongestion in humans includes menstruation, sexual arousal, REM sleep, strong emotions, illnesses and allergic reactions.

In a woman, sexual arousal leads to increased blood flow to the clitoris and vulva, as well as vaginal transudation - the seeping of moisture through the vaginal walls which serves as lubrication.

Although the clitoral body becomes engorged with blood upon sexual arousal, erecting the clitoral glans, some sources describe the clitoral glans and labia minora as composed of non-erectile tissue; this is especially the case for the glans.

Older women produce less vaginal lubrication and studies have investigated changes to degrees of satisfaction, frequency of sexual activity, to desire, sexual thoughts and fantasies, sexual arousal, beliefs about and attitudes to sex, pain, and the ability to reach orgasm in women in their 40s and after menopause.

A sexual fantasy or erotic fantasy is a mental image or pattern of thought that stirs a person's sexuality and can create or enhance sexual arousal.

Once this has started, it is likely that the man will continue to ejaculate and orgasm fully, with or without further stimulation.

A usual precursor to ejaculation is the sexual arousal of the male, leading to the erection of the penis, though not every arousal nor erection leads to ejaculation.
