- Sexual arousal
Sexual arousal is the process and state of an animal being ready for
sexual activityand feeling an urge for sexual contact.
Human sexual arousal
Sexual arousal for a man results in an increased blood flow to the
penis, to produce an erection. In a woman, the vaginabecomes lubricated in anticipation of sexual intercourse. Unlike most animals, humanbeings of both sexes are potentially capable of sexual arousal throughout the year; therefore, there is no human mating season. Things that precipitate human sexual arousal are colloquially known as turn-ons. Turn-ons may be physical or mental in nature. Given the right stimulation, sexual arousal in humans will typically end in an orgasm, but may be pursued for its own sake, even in the absence of an orgasm.
Sexual arousal causes different physical changes.
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. [cite web

Singer's model of sexual arousal
SingerSinger, B. Conceptualising sexual arousal and attraction. The
Journal of Sex Research. 1984; 20, 230-240] presents a model of the process of sexual arousal, in which he conceptualized human sexual response to be composed of three independent but generally sequential components. The first stage, "aesthetic response," is an emotional reaction to noticing an attractive face or figure. This emotional reaction produces an increase in attention toward the object of attraction, typically involving head and eye movements toward the attractive object. The second stage, "approach response," progresses from the first and involves bodily movements towards the object. The final "genital response" stage recognizes that with both attention and closer proximity, physical reactions result in genital tumescence. Singer also notes that there is an array of other autonomic responses, but acknowledges that the research literature suggests that the genital response is "the most reliable and convenient to measure" in males.
Erectile dysfunction(ED) or impotence is a sexual dysfunction characterized by the inability to develop or maintain an erection of the penis. There are various underlying causes, such as damage to the nervi erigentes which prevents or delays erection, or diabetes, which simply decreases blood flow to the tissue in the penis, many of which are medically reversible.
The causes of erectile dysfunction may be psychological or physical. Psychological impotence can often be helped by almost anything that the patient believes in; there is a very strong placebo effect. Physical damage is much more severe. One leading physical cause of ED is continual or severe damage taken to the nervi erigentes. These nerves course beside the prostate arising from the sacral plexus and can be damaged in prostatic and colo-rectal surgeries.
Due to its embarrassing nature and the shame felt by sufferers, the subject was taboo for a long time, and is the subject of many urban legends. Folk remedies have long been advocated, with some being advertised widely since the 1930s. The introduction of perhaps the first pharmacologically effective remedy for impotence, sildenafil (trade name
Viagra), in the 1990s caused a wave of public attention, propelled in part by the news-worthiness of stories about it and heavy advertising.
The Latin term
impotentia coeundidescribes simple inability to insert the penisinto the vagina. It is now mostly replaced by more precise terms.
Sexual arousal in animals
While human sexuality is well understood, scientists do not completely grasp how other animals relate sexually. However, current research studies suggest that many animals, like humans, enjoy sexual relations that are not limited to reproduction.
Dolphins and Bonobos, for example, are both well known to use sex as a "social tool to strengthen and maintain bonds." [cite video
