Unit 1: Human Sexuality and Sexual Health


This unit will cover the content of Human Sexuality and Sexual Health. This topic is more than just sex and having sex; it is part of the physical, psychological and social makeup of an individual. Sexuality is about the person you feel you are as a man or a woman, about your sexual orientation and identity. Human sexuality is a function of one’s whole personality that is life long, beginning from birth.

It includes how one feels about oneself as a person; how one feels about being a man or a woman, and how one gets along with members of either gender. Sexuality also includes genital and reproductive health, such as intercourse and child bearing. It is the way one thinks, feels and behaves (UNAIDS, 2004). Human Sexuality and Sexual Health, therefore, is the area dealing with information leading to the building of attitudes, beliefs and values about such topics as identity, body image and gender role, sexual development, reproductive health relationships, and intimacy (SIECUS, 2004).

Information on Human Sexuality and Sexual Health is crucial for preparing children for their lives as adults and parents. It will provide young people with skills such as responding adequately to demands for sexual intercourse or offers of drugs, taking responsible decisions, managing situations of risk, and seeking appropriate health services, counseling and care.

Concepts of Human Sexuality

Having understood the meaning of those two terms, let us delve deeper into Human Sexuality. It describes the direction of an individual's sexuality, often in relation to their own sex or gender. It refers to the changes that you experience when growing up, the shape of your body, the ways of dressing up, the way you talk and feel about people. In fact, it is the sum total of who you are. It comprises a whole range of behaviour and processes, including the physiological, psychological, social, cultural, political, and spiritual or religious aspects of sex and human sexual behaviour.

Many classification schemes have been established to describe people’s sexual orientations on the basis of psychological and behavioural components. Common terms for describing sexual orientation include homosexual (lesbian/gay), heterosexual (straight) and Transvestite. Another term which is becoming popular today is the term Transsexual whereby an individual can change his sex by undergoing a surgical operation. You will find more information on this section by following this LINK.

Today there is a growing concern in society about how the young generation struggles with the question of human sexuality. With more exposure to the media, young people have seen more sexual innuendo and experienced more sex earlier than previous generations and yet, they know as little as their parents knew at the age of 18. A thorough knowledge of concepts of sexuality is crucial for a healthy and balanced development of the individual.

Carry out the following activities to show that you have understood the concept discussed above:

1 List down three ways that you think you are a sexual being.

2 Think of five famous singers, artistes or other celebrities that you know and state what defines their sexuality.

3 Prepare a small speech for your friends on human sexuality highlighting the points that you have learned just now

4. Write an article for the local newspaper supporting the case that people have the right to have the sexual orientation they desire. Write another article taking an opposite stand.

Sexual Health

Also referred to as reproductive health is the many factors that will impact individual sexual function and reproduction. These factors include a variety of physical, mental and emotional issues. Disorders that affect any of these factors can impact a person's physical and emotional health, as well as his or her relationships and self-image.

Sexual health is evidenced in the free and responsible expressions of sexual capabilities that foster harmonious personal and social wellness, enriching individual and social life. It is not merely the absence of dysfunction, disease and/or infirmity. For Sexual Health to be attained and maintained it is necessary that the sexual rights of all people be recognized and upheld.

Promotion of Sexual Health



Puberty refers to the process when your body change from child into an adult and then capable of reproduction. It brings profound changes in biologic, psychologic and socilogic aspects of sexuality.

It is a period when sexuality looms and adolescents must learn to cope with their changing sexual roles and relationships and to live with their sexual urges and concerns.

Physically the body changes to a different size, shape, composition and function. But the body differences between boys and girls before puberty are almost entirely restricted to the genitalia. Boys usually start puberty at about 12 or 13 years but girls are a little earlier. This is referred to as secondary sex characteristics.

Lets take a look as to how our body changes as we are growing.

Emotions During Puberty Puberty is also the stage when important emotional changes take place. Young people get into and develop new relationships and the intensity of relationship also varies. They also become more conscious of what others think about them; the desire to be accepted and liked is strong at this stage. Some people become more important while others are held in less importance. Young boys start separating from their parents and building with other youngsters of their own age with whom they will identify. What is important at this stage is that young people begin to make decisions about what affects their life.

Many young people feel self-conscious about the changes taking place to their body and they often compare these changes with those of other people. During this period, younsters become more aware of their sexuality; their feelings are awakened and their emotions run high over things that touch them intensely especially in relation to the opposite sex. This is the time when sex and sexuality is discussed and ideas formed. They will be asking questions about masturbation, dating,kissing, having sexual intercourse, etc. For some adolescents,sexual activity may initiate psychological distress and for others they may become distress.

During puberty, females experience different changes.The emotions and subsequent behaviors protrayed may be different even between females of the same household. Some females appear quiet and withdrawn and others loud with unusual behaviors. Criticisms made to them may bring on undesireable responses. Many of them begin to take a greater care of their appearance while others seem not to care. They begin to notice the oposite sex and many of them will concentrate solely in this area. This would lead them into situations which may generally lead to trouble such as unwanted pregnancy. The cycle of sex partner change repeats itself and tend to be the downfall of such females. They also put themselves at the risk of catching a sexually transmitted infection. Their self-esteem drops and if they are within the school system their performance is generally under the expectations.

Work in groups of four people and discuss with them what you were told by family members, friends or teachers about puberty. Then compare it with what you have learn.

Sex, Pregnancy and Contraceptives

Sexual Intercourse

During adolescence, girls and boys will have some attractions for each other which will lead them to feel a sexual desire, pleasure or excitement. This excitement may lead to touching, kissing, hugging, cuddling, etc which is the beginning of sexual intercourse-foreplay. At this time both partners may reach a sexual excitement known as sexual arousal. When this happens the girls will get wet around their genitals because sexual fluids are produced in the wall of the vagina. This fluid is whitish in color. As for the boys the penis will stiff or become harder/stands up because more blood will flow in the penis. This called an erection.

Sexual intercourse or having sex is when a man inserts his penis into a woman's vagina, followed by a moment of intense sexual excitement known as an orgasm. During this act the males will release sperms and the females feel a special excitement and well being in body. Having sex can make a female become pregnant since the sperm may join with the egg to make a baby. During puberty males are capable of producing sperms that can fertilize an egg whilst women release fertile eggs until late 40s or early 50s.

In order for you to understand how pregnancy happens you need to know about the menstrual cycle. This cycle and timing of sexual intercourse is critical to the success of pregnancy or reproduction. The menstrual cycle is the time from one period to the next counted from the first day of the bleeding to the last day before the next bleeding. This takes about 28-29 days but may be shorter or longer and may change from month to month. During the first ten days the egg is nurture as it travels from the tube to the uterus. Then at the mid cycle of about 10-14 days the female is very fertile and if she is having sex the egg can be fertilized by the sperm/egg of a man. After about 14 days if the egg has been fertilized, the egg will then stick to the lining of the uterus and grows into a baby.

If the egg is not fertilized the uterus will pick up that nothing has happened and the egg along with the lining of the uterus will break and pass through the vagina in the form of blood.

You can read more on the menstrual cycle if you click on the following link.

Using a calender and the knowledge of the menstrual cycle, discuss the process of the menstrual cycle.

Drug Use and Sex The unacceptable habit of drug use and abuse has a serious impact on the sexual experiences and its outcomes. Individuals who have sex under the influence of marijuana, alcohol, cocaine, heroin, crystal meth and others, may experience a great deal of pleasure but would also behave in a very irresponsible manner since their thoughts of self self control and and acceptable behaviour are non-existent. Sex, therefore must be under the control of a rational individual and not under the conditions in which there is no responsible behaviours.


Contraceptives are medications or tools that are used to prevent pregnancy. That is it prevents a man's sperm from coming together/joining with the woman's eggs. People use contraceptives to prevent unplanned pregnancy. Not all methods of contraceptives will protect you from sexually transmited diseases or HIV/AIDS. There are different methods of contraceptives but we will be discussing the most commonly used ones.

Common Methods Condom is a contraceptive that is put on the erect penis just before having sex. This is a barrier method that is made from thin rubber and is use only once and discard. This method would prevent semen from entering the vagina, the anus or the mouth. This is one method that can protect you from pregnancy, STI and HIV.

Femidom This is the female condom that is inserted into the vagina up to 8 hours before sex or shortly before sex. It is bigger than a male condom and it has two plastic rings on each end. As with the condom this can only be used once and discard. It works similar to the male condom in that it prevents the exchange of body fluids. This method protects you from pregnancy, STI and HIV.

PillThis is a tablet to be taken by a woman every . It prevents a woman's ovaries to release an egg every month. So if there is no egg release she cannot fall pregnant. This contraceptives can prevent pregnancy but not STI/HIV.

Sexually Transmitted Infections(STI)

It is also commonly known as sexually transmitted diseases. These are diseases that are passed on from one person to another through sex including vaginal, oral and anal sex. Some STD are relatively harmless and can be treated e.g. candidiadis, chlamydia. Others such as gonorrhea, genital, herpes, syphillis and HIV/AIDS are much more danger. If an STI is not treated you can have serious consequences such as damage to the reproductive organs resulting in fertility.

HIV stands for Human Immunodeficiency Virus It is the virus that causes AIDS-Acquired Immunodeficiency Syndrome'. This virus only infects humans and slowly weakens the body's immune system. That is it makes the body vulnerable to different illnesses and eventually causing deaths.

If you are infected with HIV you will eventually develop AIDS. It can take between 2-10 yeras to develop AIDS after been infected with the HIV.There is treatment for HIV/AIDS but no cure, therefore you must protect yourself from getting the virus.
