Phases of sexual response cycle

Sexual Stimulation Phase

It is also known as arousal or initial excitement phase.

Erogenous zones: are highly innervated areas of the body that are especially sensitive and responsive to sexual stimulation, thus causing sexual arousal and sexual pleasure. Common areas identified as erogenous zones include the neck, earlobes, mouth, lips, nipples, genitalia, buttocks, inner thighs, anus, back of knees, fingers, and toes.

Erotic fantasy: means reading, watching, watching, imagining, telling, or acting out erotic fantasies with or without a partner.

Erotic massage: is the sensual and sexually amusing body massage, which sometimes includes stimulation of the sexual organs with hands, body, or mouth.

Erotic: refers to something or someone tending to arouse sexual desire.

Exhibitionism: refers to undressing, performing sex acts, or masturbating in front of others, or by exposing one’s genitalia to strangers as a means of obtaining sexual arousal.

Foreplay: is the physical and sexual stimulation (such as kissing, touching, stroking, and massaging) usually preceding sexual intercourse.

Cunnilingus: is the stimulation of the external genitalias of the woman with lips, mouth, or tongue.

Fellatio; is the stimulation of penis using the lips, mouth, or tongue.

Fetishism: refers to the sexual arousal occurring in response to any nonsexual object or practice or to a non-genital body part.

 Masturbation: refers to the manual stimulation of oneself or of a partner for sexual pleasure. 

Sexual excitement phase

Excitement (arousal): is the second stage of the sexual response cycle, which is characterized by increased heart rate and blood pressure, body muscle tension, sexual flush, and erection of nipples in both sexes. In women, vaginal lubrication and swelling of the vulva also occur. In men, there is scrotal thickening, and movement of the testes closer to the body.

Plateau Phase is the Part of Excitement phase?

The plateau phase is the period of sexual excitement prior to orgasm.

How is erection occur?

It is initiated by dilation of the arterioles of the penis. As the erectile tissue of the penis fills with blood, the veins are compressed, blocking outflow and adding to the turgor of the organ. It is due to phychological

Erection: is the firm and enlarged condition of a body organ (e.g., penis, clitoris, nipples) when the erectile tissue surrounding it becomes filled with blood.

Orgasmic Phase

The orgasm is the climax of the sexual response cycle. It is the shortest of the phases and generally lasts only a few seconds.

What is Orgasm?

An orgasm is the pleasurable release of built-up muscle tension that can happen from any kind of sexual stimulation. Guys tend to reach orgasm more quickly and easily than women (although this isn't true for everyone). And women are more likely to orgasm from stimulation of the clitoris than the vagina.

During an orgasm, you may feel warm, your heartbeat will race, you'll breathe harder, your face and chest might get flushed, and you'll have muscle spasms in your genitals. It's often intense and feels really good.

Men usually ejaculate when they orgasm. Some women ejaculate during sexual activity, too. Most women don't ejaculate, but either way is normal.

What is ejeculation?

It is the moment when rhythmic contractions of the urethra cause semen to be discharged from the penis.

Ejeculation is a two part spinal reflex that involves emission, the movement of the semen into the urethra and ejaculation, the propulsion of the semen out of the urethra at the time of orgasm. It can happen during the time of sleep which is called as “wet dream”

Although people tend to think that having an orgasm is the "goal" of sex, many women and men get lots of pleasure from doing sexual things even if they don't have an orgasm. Many people masturbate to release sexual tension and to have an orgasm.

Phase of resolution

The resolution phase occurs after orgasm and allows the muscles to relax, blood pressure to drop and the body to slow down from its excited state.
