Study Notes
Physical Self
- Refers to the physical or tangible parts of a person, including the body's organs and features.
- It is the aspect of a human that can be touched and seen, unlike mental, emotional, or spiritual aspects.
Sexual Self
- Encompasses a person's understanding of their sexuality, including preferences, self-perception, and how they express their gender.
- This aspect involves learning about sexual development and how societal beliefs can affect personal views and expressions of sexuality.
Sexual Dimorphism
- Refers to the physical differences between males and females.
- Men typically have taller height, heavier bone structures, stronger musculature, and larger hearts and lungs compared to women.
- Women, on the other hand, generally have a higher percentage of body fat than men.
- These physical variations are influenced by hormones that cause changes throughout life.
Sex Determination
- During the first six weeks of pregnancy, the fetus's gender is not yet determined, and its organs are not fully developed.
- If there are disruptions or abnormalities in sex hormone production, it can lead to unusual physical characteristics.
Pseudohermaphrodites
- Refers to individuals whose external genitalia do not align with their gonadal sex.
- This means their physical sex characteristics (genitals) may not match their internal reproductive organs (ovaries or testes).
Genetic Sex Determination
- Females have XX chromosomes, while males have XY chromosomes.
- Testosterone is the dominant male hormone, whereas estrogen and progesterone are the dominant female hormones.
Puberty and Sex Hormone Production
- During puberty, the sex glands (ovaries for females and testes for males) become active, leading to an increase in sex hormone production.
- This surge in hormones triggers the development of secondary sexual characteristics, including menstruation in females and nocturnal emissions (wet dreams) in males.
Human Sexuality
- It involves a complex interplay of biological sex, core gender identity, and gender role behavior.
- It is influenced by a combination of biological, physiological, and psychological factors.
Erogenous Zones
- These are parts of the body that, when touched in a sexual manner, cause heightened sexual arousal.
- These areas vary from person to person but often include the mouth, breasts, genitals, and anus.
Human Sexual Behavior
- Any activity, whether solitary, between two individuals, or in a group, that involves sexual arousal.
- Two primary factors influence human sexual behavior:
- Inherited Sexual Response Patterns: These are innate responses that can be passed down genetically.
- Extent of Expression: This aspect is influenced by cultural values, beliefs, and societal norms.
Types of Human Sexual Behavior
- Solitary Behavior: Involving one person, such as masturbation.
- Sociosexual Behavior: Involving multiple people, such as threesomes or group sex.
Physiology of Human Sexual Response
- The process of physical and emotional changes that occur during sexual arousal and engagement.
- Understanding the sexual response cycle can enhance relationships and ensure appropriate behavior during each phase.
The Four Stages of the Sexual Response Cycle
- Excitement Phase: Increased heart rate, blood pressure, and skin temperature. Muscle tension, and the influx of genital fluids.
- Plateau Phase: A brief stage that signals an approaching orgasm if stimulation continues.
- Sexual Climax (Orgasm): A surge of intense pleasure, accompanied by rapid heart rate, blood pressure, and muscle spasms in the pelvic area. This stage includes contractions in the female reproductive organs and ejaculation in males.
- Resolution Phase: The body returns to its normal state after the climax.
Male Sexual Disorders
- Male Hypoactive Sexual Desire Disorder: Reduced or absent interest in sexual activity.
