Document Summary

In most animals, brain controls and regulates sexual behavior largely through hormones and neurotransmitters. Neurotransmitters are chemical messengers that affect sexual desire, arousal, orgasm, and our desire to couple with certain partners. Testosterone is the most influential hrmon in the sexual behavior of both men and women, however estrogen also regulates sexual behavior in both sexes. Our family of origin, our ethnicity and our religious background are our first points of reference for sexuality. It is where we learn to internalize norms about sexual attitudes and behaviors. Race has been found to be one of the most influential variable that affect both sexual attitudes and behaviors. Sexual response is a series of physiological and psychological changes that occur in the body during sexual behavior. Masters and johnson created a four-phase sexual response**** Primary physical change that occurs is vasocengestion, an increase in blood concentrated in genitals, breasts, or both. Vasocengeston cause vaginal walls to begin lubrication, process called transduation.
