WS 350 Quiz 7: Sexual Response

Research has shown, that during penetration additional clitoral stimulation is more than often (more than 70% of the cases) needed for orgasm to occur. True False

True

When engaging in penetrative behaviors, it is important to remember that it often takes longer for the vagina and/or anus to reach the state where penetration is comfortable and pleasurable in comparison to the relatively short time it takes for the penis to become erect and ready for penetration. Communication is essential in this process making sure that sufficient levels of arousal and excitement have been reached before penetration begins to ensure that both the receiver and the inserter derives pleasure from the penetration. True False

True

Masters and Johnson identified four stages of human sexual response. Please rank them in the correct order of appearance: 1st ______ 2nd ______ 3rd ______ 4th ______

Which of the following organs have the sole purpose of producing pleasure? A. Clitoris B. Penis C. Brain D. Anus

Helen Singer Kaplan criticized Masters and Johnson's four-stage model of sexual response and stated that humans have what she refers to as a "brain appetite" for sex. To illustrate this, she developed a tri-phasic model of sexual response that included a phase to recognize this brain appetite, what is the name of this phase? A. Desire B. Excitement C. Arousal D. Pleasure

A. Desire

1. Plateau phase 2. Resolution phase 3. Orgasmic phase 4. Excitement phase

A. During this phase, there is an increase in pulse, respiratory, and heart rates. The testes elevate closer to the body and there is an increased tenting effect. The sympathetic part of the nervous system is most dominant in this phase. D. During this phase, detumescence occurs. The pulse, heart, and respiratory rates drop, and muscles begin to relax. A deep sense of bodily satisfaction occurs. The parasympathetic part of the nervous system is most dominant in this phase. B. This phase involves a highly pleasurable response involving the feeling of physiological and psychological release from maximum levels of sexual excitement. The sympathetic part of the nervous system is most dominant in this phase. C. During this phase, tumescence begins causing the penis to become erect and the vagina begins to widen and lengthen. The parasympathetic part of the nervous system tends to be most dominant, particularly in the early stages of this phase.

A sex flush may appear during the excitement phase, usually on the cheeks of the face or the chest.
