Human Sexuality

...SEXUALITY AND SEX I. Definition Human sexuality is the expression of sexual sensation and related intimacy between human beings. Psychologically, sexuality is the means to express the fullness of love between a man and a woman. Biologically, it is the means through which a child is conceived and the lineage is passed on to the next generation. And it involves the body, mind, and spirit. There are a great many forms of human sexuality, comprising a broad range of behaviors, and sexual expression varies across cultures and historical periods. Yet the basic principles of human sexuality are universal and integral to what it means to be human. Sex is related to the very purpose of human existence: love, procreation, and family. Sexuality has social ramifications; therefore most societies set limits, through social norms and taboos, moral and religious guidelines, and legal constraints on what is permissible sexual behavior. DID YOU KNOW? Human sexual activity is more than a physical activity; it impacts the minds and hearts as well as the bodies of the participants. People may experiment with a range of sexual activities during their lives, though they tend to engage in only a few of these regularly. However, most societies have defined some sexual activities as inappropriate (wrong person, wrong activity, wrong place, wrong time, and so forth).The most widespread sexual norm historically, and the norm promoted nearly universally by the world's religions, is that sex is appropriate...

Persuasive Speech About Sex

...Section All About Sex Am I ready for it? What should I do if I think I'm ready for it? Should I talk to my parents about it? How do I talk with my parents about it? There are different kinds of sex — but you need good communication and consent no matter what kind of sex is involved. Sex can lead to pregnancy and/or STDs, but there are ways to protect yourself.

...10 Surprising Health Benefits of Sex The health benefits of sex extend well beyond the bedroom. Turns out sex is good for you in ways you may never have imagined. 1. Sex Relieves Stress A big health benefit of sex is lower blood pressure and overall stress reduction, according to researchers from Scotland who reported their findings in the journal Biological Psychology. They studied 24 women and 22 men who kept records of their sexual activity. Then the researchers subjected them to stressful situations -- such as speaking in public and doing verbal arithmetic -- and noted their blood pressure response to stress. Those who had intercourse had better responses to stress than those who engaged in other sexual behaviors or abstained. Another study published in the same journal found that frequent intercourse was associated with lower diastolic blood pressure in cohabiting participants. Yet other research found a link between partner hugs and lower blood pressure in women. 2. Sex Boosts Immunity Good sexual health may mean better physical health. Having sex once or twice a week has been linked with higher levels of an antibody called immunoglobulin A or IgA, which can protect you from getting colds and other infections. Scientists at Wilkes University in Wilkes-Barre, Pa., took samples of saliva, which contain IgA, from 112 college students who reported the frequency of sex they had. Those in the "frequent" group -- once or twice a week -- had higher levels of IgA than those...

Sexual Morality

...in Ethics while attending Bible College, and I thought the information would be good discussion material.  I do not recall the source material. If anyone recognizes any of this, please let me know, so I can attribute it appropriately. I wanted to discuss the ethics involved in sexual morality, specifically adultery and fornication.   The issue is whether it is morally right to engage in sexual relations outside of marriage.  This entails both adultery, which is sex between a married person with someone other than one’s spouse, and fornication, which is sex between unmarried people.  There is one position that holds that sex outside of marriage is not a good thing, while there are two views that consider fornication to be morally right, the natural impulse view and the affection view. The basis for the natural impulse view on sexual morality is that sex, which as a impulse or instinct and completely natural, should be enjoyed to obtain the greatest happiness.  Contraceptives remove the concern of unwanted pregnancy or sexual disease.  Sex should be considered a pleasurable physical activity, with no moral guilt attached to it, as long as both partners voluntarily engage in it without the involvement of harm or deceit.  There is no need to restrict sexual fulfillment to a single partner nor is there a requirement that sex be accompanied by love.  There are four arguments for this position: 1.     Sex is an impulse or instinct, which is natural and should be followed, much like...

Sex Education

...Anne G. Taisacan Professor Noha Kabaji English C100 Sex Education “Sex education is a process of life – nutrition, respiration, excretion, sensitivity, movement, growth and reproduction. As parents we teach, guide and nurture our children through childhood and adolescence towards adulthood, providing them with the skills and knowledge to make safe choices on the food they eat, the sports they participate in and safe personal hygiene. Sex education is not about giving people the facts; it is also about teaching skills to enable young people to use that information effectively and to moderate behaviors according to the information and knowledge at hand.” Every parent knows that there are lots of responsibilities when it comes to nurturing and discipline. Since sex education is a sensitive topic, a lot of controversy emerged concerning the right age for teenagers to explore sex education and the appropriate approach for the adolescence to understand the purpose of the topic. The increase of teen pregnancy and sexual transmitted disease among adolescence brought attention to the society. To prevent or to reduce the incident, the government recommended adding sex education to the curriculum. By providing the right information to teens will prevent or reduce the number of teen pregnancy and other health issues they might face. However, despite of the good intention, their are other parents or organization disagree with sex education because of their religious beliefs or culture...

Premarital Sex Premarital Sex and Religion The Catholic Church teaches that premarital sex is wrong, yet it is still widely practiced around the world. The reason marriage was created was to join two people of the opposite sex together in a holy sacrament that would make the couple one. God's reason for marriage is quoted in the bible when he said, "For this reason a man shall leave his father and his mother and be joined to his wife, and the two shall become one flesh" . The Sacrament of marriage is one of the most sacred Sacraments in the Catholic Religion. By performing premarital sex, the couple is breaking a covenant with God and is performing a sin. Marriage is the joining of a couple in the eyes of God and in the eyes of the State. When two people are joined into marriage they become on in flesh and one spirit. Sexual intercourse within marriage is for this reason good and of great blessing both to...

Who Should Teach Children About Sex and Sexuality?

...Who should teach children about sex and sexuality? Children of these generations are having more access to all kinds of information including sex and sexuality than past generations. They can get sexual information from school, parents, friends, and even from Internet. Talking about sexuality is always been a hard topic that concerns mostly schools and parents. But who are the right teachers that should tell everything about sex and sexuality to the children? After asking me this question many times, I believe that parents should teach their own children because they are the role models to the children, give them the right information, and protect them. Schools still need to have sex education programs, but parents are the ones who are primarily responsible. I know in all schools, people are teaching about sex and sexuality to the children, and there is nothing wrong with that; they actually teach sexuality in schools because for many parents is just impossible to explain their own kids or sometimes they don’t seem to care. I believe parents should teach their children because they are the role models to those children. To me the house is the first school, and is the place where you grow and learn many things from your parents. In my opinion, it will be better for the kids to learn about this topic from their parents than strangers in the school. My parents never told me anything about sex; I learned from school, but I would it like them to teach me because they were...

Theology of Sex

...Literature 28 January 2010 Sex’s Purpose Like any good essay on theology it’s always good to start at the beginning, the creation narrative. In our Judeo-Christian understanding God, at his creating the earth and everything in it, created also man and woman. He created them in his very image, thus imparting to us many of his “spiritual” attributes with the life of His breath noted in Genesis 2. God then commissioned His people to procreate saying, “Be fruitful and multiply” (referring then to their natural ability to participate in the act of sexual intercourse. However, the concept of their sex was more than just the act but also their being created together out of one and as one. After reading through this story and several other references I’ve come to the conclusion that sex is NOT intercourse but an expression of relationship. Brueggemann supports this noting that the Old Testament considers “sexual relations [as] the most intimate, treasured, costly, and demanding of all relationships.” (194) Sex is an expression of love, and love is the root of any relationship. When sex becomes removed from love, a relationship becomes diminished. My exploration into sex has resulted in me seeking an understanding of right relationship, knowing how sex fits into it. Our being image-bearers of God was a striking feature as I started my research and what it implies for our “sexuality”. In the Dictionary of Biblical Imagery, the topic of sex opens with a comparison of the Creation narrative...

Sex Sells and Ethics

...Sex Sells and Ethics “In our day to day lives, we always face situations were we have to make decisions and decide what is right and wrong. We are always faced with the debate of what is moral or immoral, ethical or unethical”[The Ethical Dilemma of Advertisements]. Is it ethical to implement the ideal “sex sells” within Marketing? In order to answer the posed question, one must first define ethics. Ethics as outlined in Marketing the Core is “the moral principles and values that govern the actions and decisions of an individual or a group”. Although ethical choices stem from your personal moral philosophy, which can be categorized into two ideals: moral idealism, a “personal moral philosophy that considers certain individual rights or duties as universal, regardless of the outcome”[Marketing the core]. Where as utilitarianism is a “personal moral philosophy that focuses on the ‘greatest good for the greatest number’”[Marketing the core]. Sex appeal can be defined as messages, whether as brand information in advertising contexts or as persuasive appeals in marketing contexts, which are integrated with sexual information, in particular, this appeal can be defined as the degree of nudity or sexual explicitness in an Ad, It can be found in the visual, audio, and verbal elements of advertisements.[Liu&Li&Cheng2006] In Mark Levit’s Article: Sex in Advertising: Does it Sell? he explains “Sex appeal can increase the effectiveness of an ad or commercial because it attracts...

Gay Marriage

...Same sex marriage as defined in our text book, Doing Ethics, refers to the marriage in a full legal sense of gay and lesbian couples. (Vaughn 2013, p 451) Marriage between a man and a woman was instituted by God with Adam and Eve. According to the scripture, Matthew 19: 4-5, New Testament, Jesus reaffirms this “He answered, Have you not read that he who made them from the beginning made them male and female: and said, “For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one?” However, the media is supportive and liberal in their views of views if same-sex marriage. Even the Merriam-Webster dictionary defines marriage as the state of being united to a person of the opposite sex as husband and wife in a consensual and contractual relationship recognized by law. But as the second definition, it states, the state of being united to a person of the same sex or a relationship like that of a traditional marriage. Same-sex marriage is one of the most controversial issues in the world. According to our text book, Doing Ethics, William Bennett warns of the dire consequences of legalizing same sex unions. He states that “the legal union of same-sex couples would shatter the conventional definition of marriage, change the rules which govern behavior, endorse practices which are completely antithetical to the tenets (a principle or belief, especially one of the main principles of a religion or philosophy) of all the world’s major...

These factors have changed my mind about sex. It wasn’t a very big deal for me till I was in the 8th grade.

Film Critique

...Destiny Matvenko-Barbini AP/HREQ 1800 Veronika Novoselova York University Film Critique: The Education of Shelby Knox The film The Education of Shelby Knox is a documentary that tells a story of a girl named Shelby, who tries to fight to have sex education put into public schools of Lubbock, Texas by joining a youth commission. By joining the youth commission and trying to campaign the right to get sex education, there were a few bumps in the road, like having the campaign also fight for gay rights. But nothing stopped her and she kept fighting. The central theme of this film is the lack of sex education, and not having it in public schools. This theme is important because Shelby thinks it would be a good idea to add it so more people to have a better understanding of what sex really is. Throughout the film, the lack of sex education can be analyzed by what social issues it causes and why the issues are important, how sex education challenges the notion of child innocence, the sociological concepts that are helpful in understanding the film’s message and what king of social impact the film seeks to achieve and examine what questions for further discussions it rises. By analyzing this, it will give us an indication on why sex education should be put into the schools of Lubbock. In the film, according to Shelby, “one in fourteen teenage girls getting pregnant” (The Education of Shelby Knox), in Lubbock, Texas, which leads to the key social issues that are portrayed in the...

Same Sex Marraige

...Merrie Hill Final research paper Same sex marriage has been a hot topic in the news lately, as well as in the political arena. Marriage between a man and a man or a woman and a woman are felt by many to be morally wrong, but is it really? Or do these people fear the unknown and are using morality as the excuse for their negligence of the unknown? The utilitarian follow the utilitarian moral guide lines in their beliefs utilitarian’s would not be against same sex marriages. However if the Ethical egoist follows their moral guide lines then it is believed that they would be against same sex marriages. In this paper I am going to try to show you what has brought me to these beliefs and how I believe ones morals may differ in the pursuit of society’s happiness. Utilitarianism is about obtaining the greatest good for the greatest number of people. With that said utilitarian’s would not be against two people in love, joining together in the sanctity of marriage. According to Webster’s dictionary utilitarianism is defined as: “a theory that the aim of action should be the largest possible balance of pleasure over pain, or the greatest happiness of the greatest number.” Our ethic’s book Ethics Theory and Practice tenth edition (Thiroux and Krasemann 2009 page 317), “the basic argument against the morality of homosexuality is that it is unnatural and perverse; that is, it...
