females, the clitoris retracts under the clitoral hood and the inner two-thirds of the vagina is fully extended causing a “tenting” effect and forming the seminal pool. The outer third of the vagina becomes engorged with blood forming the orgasmic platform and in the breasts the areolae increase in size. For females, the plateau phase can supply adequate sexual satisfaction and they consequently skip the orgasm phase altogether. As with the excitement phase, both sexes experience an increase in heart rate, blood pressure and respiration rate.The orgasm phase is the third phase of Masters and Johnson’s model on sexual response (Greenberg et al., 2014). In males, the orgasm phase is a two-part process involving emission andexpulsion. During emission, the muscles of the vas deferens, the seminal vesicles and the prostate contract building up semen while the external and internal urethral sphincter contract holding in the sperm and stopping it from entering the bladder. The buildup of semen causes a feeling of immediate ejaculation that leads to the expulsion part of the orgasm phase for males. During expulsion, the internal urethral sphincter remains contracted while the external urethral sphincter releases ejecting semen from the urethral opening. In females, contractions occur at theorgasmic platform, the anal sphincter, and in the uterus beginning at the top. Some women skip this phase altogether and are sexually satisfied after reaching the plateau phase. For both males and females, heart rate and blood pressure increases and perspiration can often occur. Both sexes are often filled with pleasant psychological feelings that coincide with the release of sexual tension.The final phase of the Masters and Johnson model on sexual response is termed the resolution phase which brings males and females back to an unaroused stated (Greenberg et al., 2014). Returning to the unaroused state for males means a rapid decrease in size of the testicles and penis with the testicles moving further away from the body and loss of penile erection. Men
