Sexual Response Cycle

Sexual Response Cycle:   Assignment

    The sexual response cycle depicts the changes that come about to men and women during sexual arousal.   There are four levels to the sexual cycle:   excitement, plateau, orgasmic, and resolution.   Sexual response cycle is also characterized by vasocongestion, which is muscle tension that can cause tremors and spasms.
    During the first phase of the sexual response cycle “excitement”, vasocongestion causes erections in men, a swelling of the testes, and causes the crotal skin to tighten.   For women in this phase, vaginal lubrication will start and vasocongestion will cause the clitoris to swell and the vaginal lips to spread and flatten.   Also in this phase, the breast will enlarge and blood vessels may become more prominent.   Both men and women will share commonality of muscle tension and an increased heart rate during this phase of the cycle.
    In the second phase of the sexual response cycle “plateau”, both men and women will experience heavier breathing and increase heart rate.   The testes may reach up to one and half times their un-aroused size, and are elevated into position for ejaculation.   The inner two-thirds of the vagina expand in women; vasocongestion swells the outer part of the vagina, contracting the vaginal opening in preparation for grasping the penis.   The inner part of the vagina expands further and the clitoris withdraws beneath the clitoral hood and shortens.   In both men and women, their breathing becomes heavier and rapid; and their heart rate may increase 100 to 160 beats per minute.   In both men and women, the blood pressure will continue to rise.
    The third phase of the sexual response cycle “orgasmic”, the release of the sexual tension that is accompanied by feeling of intense pleasure in both men and women.   Both men and women will also experience muscle spasms and their heart rate, blood pressure, and breathing will reach a peak.   Women will usually experience 3-15 contractions about...
