minora, and clitoris. The uterus is lifted up, increases in size, and vaginal secretions increase. The nipples harden and become erect. The next phase is the plateau phase. This happens just before an orgasm with increasing stimulation of the genitals. Muscle tension further increases and involuntary vocalizations occur. Being in this phase too long will lead to some people feeling uncomfortable and sexually frustrated. Males in the plateau phase have contraction of the urethral sphincter to prevent semen from mixing with urine. Rhythmic contraction of the pelvic muscles begins and preejaculate can be released. In women, the clitoris is increasingly sensitive and there is increased lubrication. This is the peak of sexual excitation if an orgasm isn’t reached. The orgasm phase involves cyclical contraction of the anal and perineal muscles, uterine contractions, and vaginal contractions. Muscle spasms happen throughout the body, the heart rate increases further and a sensation of euphoria is experienced. Males will ejaculate during orgasm. Women also experience the same sexual pleasure as men, even though most do not ejaculate.
MORE ON ORGASM Orgasm is also referred to as sexual climax. It discharges the sexual excitement built up in the excitement and plateau phases of the sexual response cycle. Its physiological activity is under the control of the autonomic nervous system. There is a natural euphoric response that releases oxytocin, prolactin, and endorphins, which contribute to a relaxing experience. The muscular contractions, particularly of the pelvic muscles, are a key feature of an orgasm, which help to dissipate sexual tension. The exact definition of what an orgasm is cannot, however, be agreed upon by doctors and researchers. There are physical, neurological, endocrine, and psychological definitions included under the umbrella of the word “orgasm”. An orgasm can be achieved with anal, vaginal, oral sex. It can also be achieved without penetration and can involve both masturbation and sex toys. While orgasms usually
