Excitement in Orgasms part 2 of 3
This is a guest blog submission by Climax Connection member, eric60red.
It’s All Very Arousing – Sexual responses may be either psychogenic or reflexogenic in nature. When erection occurs as the result of direct physical stimulation, it is known as a reflexogenic erection. When an erection results from erotic thoughts or viewing erotic material, it is known as a psychogenic erection. Sexual arousal in the female may also be either psychogenic or reflexogenic in nature and is typically associated with an increase in vaginal lubrication.
Excitement Stage – In the male, direct genital stimulation usually causes an erection within a few seconds. An erection is the result of an increase in blood flow to the penile blood vessels and tissue. In addition to erection, the excitement stage in the male is characterized by the testicles being pulled closer to the body and a tensing and thickening of the skin of the scrotum. The muscles of the body also begin to tense up, and the heart rate, breathing rate, and blood pressure begin to increase. Some males may also experience nipple erection and a reddening of the skin of their face, chest, and neck during the excitement phase. The reddening of the skin, which is similar in appearance to a measles rash, is known as a sex flush and is usually more predominate in females.
Turn Me On – In the female, the excitement stage of sexual arousal is characterized by the onset of vaginal lubrication, clitoral erection, changes in the size and shape of the labia, nipple erection, and swelling of the breasts. Women also experience the build-up of muscle tension and an increase in the heart rate, breathing rate, and blood pressure.
Plateau Stage – In both the male and female, the plateau stage is associated with further increases in muscle tension, heart rate, breathing rate, and blood pressure, as well as an increase in the intensity of the sex flush. In the male, the glans (head) of the penis turns a deeper red or purplish colour, and a few drops of slippery fluid (often referred to as “pre-cum” or “love drops”) may be released from the urethra. In the female during the plateau phase the labia appear darker in colour, the clitoris retracts, and small glands outside the vaginal opening secrete a mucus-like fluid.
Orgasm Stage – For the male, orgasm almost always includes ejaculation, which occurs in two distinct stages: emission and expulsion. Emission occurs when semen collects in an upper part of the urethra known as the urethral bulb. As more semen collects in the urethral bulb, he develops the feeling he is about to ejaculate. This feeling is known as ejaculatory inevitability and usually lasts for 2 to 3 seconds. This is the “point of no return” — the man cannot be stopped from having the orgasm at this point. Expulsion, the second stage, involves rhythmic contractions of the muscles around the base of the penis and anus. These muscular contractions cause the semen to be propelled down the urethra and out of the body. There are normally 4 to 5 rhythmic contractions that occur at 0.8-second intervals, with the first ones being the strongest and most intense. During orgasm in both males and females the heart rate, blood pressure, and breathing rate all reach peak levels. Both males and females also release a hormone known as oxytocin from their posterior pituitary glands. This hormone is believed to help strengthen the pelvic-muscle contractions associated with orgasm.
