Sexuality: The Biology of Sex
Almost everyone understands what sex is, to make humans and animals have children. But today the definition of sex is taken into a different view. We not only have sex to reproduce but we have sex for our own personal pleasures now. We don’t need to have sex daily to survive like water and food but we have sex because, bottom line, we can. The biology of sex deals with the brain areas sex is involved in, what roles hormones play in sexual motivation and the nature of the human sexual response pattern. The human sexual response pattern addresses the psychological and emotional aspects of desire, as well as the physical experience of arousal, reaching a plateau, having an orgasm (with or without ejaculation), and experiencing resolution, during which the body returns to its previous, unaroused state (1996). Human sexual response pattern goes threw four stages; excitement, plateau, orgasm, and resolution. The excitement stage involves the rushing of blood flow into your genital area which gives an erotic response for several minutes to several hours. The second stage is the plateau and it includes heavy breathing, increased heart rate, higher blood pressure, and almost reaching an orgasm. Then the third stage, orgasm, gives a person 3-25 seconds of bursting pleasure. After the orgasm comes the final stage of resolution. This is when your blood pressure goes back to normal, but at this stage it is different for females and males. Females could go and repeat the first three stages again, were as males it takes them a much longer time before they can engage in sex again. These are the key issues why we want to have sex for pleasure and not only for reproducing. The biology of sex deals with the brain areas sex is involved in, what roles hormones play in sexual motivation and the nature of the human sexual response pattern. So maybe next time before having sex, you can think about how your body is functioning.
