Study Notes
Secondary Sex Characteristics
- Secondary sex characteristics are physical traits that develop during puberty and are not directly involved in reproduction, but rather distinguish males from females.
- Examples of secondary sex characteristics include:
- In males: Facial hair, deepening of voice, increased muscle mass, and broader shoulders.
- In females: Breast development, widening of hips, and fat distribution changes.
Human Sexual Response Cycle
- The human sexual response cycle consists of four main phases:
- Excitement Phase: Characterized by physiological arousal, including increased heart rate, blood pressure, and muscle tension.
- Plateau Phase: A period of heightened arousal, where the physical changes from the excitement phase intensify.
- Orgasmic Phase: Marked by intense pleasure and involuntary muscle contractions, leading to release of sexual tension.
- Resolution Phase: The body returns to its pre-arousal state.
Hormones and Love
-
Helen Fisher's Theory of Love Stages:
- Lust Stage: Characterized by attraction and sexual desire, primarily driven by testosterone.
- Attraction Stage: Focuses on intense infatuation and romantic feelings, influenced by dopamine and norepinephrine.
- Attachment Stage: Marked by feelings of comfort, security, and bonding, associated with oxytocin and vasopressin.
Erogenous Zones
- Erogenous zones: Areas of the body that are particularly sensitive to touch and stimulation, leading to sexual arousal.
-
Common erogenous zones:
- Genitals
- Breasts
- Neck
- Lips
- Ears
- Inner thighs
Sexual Play and Reproduction
- Sexual play: Activities that can be physically intimate and pleasurable, but do not necessarily involve sexual intercourse.
- Primary function of the human reproductive system: Production of sex hormones and gametes (sperm and egg), facilitating sexual reproduction.
Hormones and Behavior
- Fight or Flight Response: Triggered by stress and fear, leading to the release of adrenaline (epinephrine) and noradrenaline (norepinephrine).
- Testosterone: Primarily responsible for male sexual development and characteristics. It plays a role in libido, muscle growth, and bone density.
- Oxytocin: Released during orgasm, promoting feelings of intimacy, bonding, and trust.
Influencing Factors in Sexual Behavior
- Biological Factors: Genetics, hormone levels, and neurotransmitters influence sexual behavior and preferences.
Key Considerations
- Individual Variation: The human sexual response cycle is not uniform, and individuals may experience different stages or lengths of time within each phase.
- Sexual Diversity: Sexual behaviors, preferences, and identities vary greatly among individuals and cultures.
