Sexual arousal

Sexual arousal is the process and state of an animal being ready for sexual intercourse.

Human sexual arousal

Unlike most other animals, human beings of both sexes are potentially capable of sexual arousal throughout the year, and there is therefore no human mating season. Things that precipitate human sexual arousal are commonly known as turn-ons. Given the right stimulation, sexual arousal in humans will typically end in an orgasm, but may be pleasurable for its own sake, even in the absence of an orgasm.

Causes of human sexual arousal

• The sight (including eye contact), smell, warmth, and touch of a (potential) sexual partner
• Sexual foreplay
• Erotic thoughts, fantasies or dreams
• Presence of fetishised objects
• Pornography
• Erotica
• Sex in advertising
• Masturbation
• Sexual roleplaying
• Voyeurism

Signs of possible human sexual arousal

• Among both genders
• *Increase in breathing rate
• *Increase inblood pressure
• *Increase in muscle tone (myotonia)
• *Increase in heart rate (tachycardia)
• *Vasocongestion of the skin ("sex flush")
• *Slight or extreme dilation of the pupils (though especially so with females)
• *Erection of the nipples (especially upon direct stimulation)
• Female sexual arousal:
• *Increase in breast size
• *Lubrication of the vagina
• *Vasocongestion of the vaginal walls
• *Clitoral tumescence and erection
• *More visible venous patterns across the breasts
• *Elevation of the uterus and stretching of the vagina
• *Change in shape and size of the labia majora and labia minora
• Male sexual arousal
• *Penile tumescence and erection
• *Emission of pre-ejaculatory fluid
• *Ascension of the testes
• *Tensing and thickening of the scrotum

Human sexual response cycle

During the 1950s and 1960s, William H. Masters and Virginia E. Johnson conducted many important studies within the field of human sexuality. In 1966, the two released a book, "Human Sexual Response", detailing four stages of physiological changes in humans during sexual stimulation. These phases, in order of their occurrence, are excitement, plateau, orgasmic, and resolution.

Genital procedures and sexual arousal

Scientific data shows that male circumcision causes neurological changes in the human brain, which is suggested to lower sexual excitability (Mackey, 1997). http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cm... Another study suggested that arousal of a man's female partner is also impacted. http://www.nzma.org.nz/journal/116-1181/595/
