Understanding the Biological Aspects of Sex
The Science Behind Human Sexual Response
Human sexual response involves a complex interplay of physiological and psychological factors. The typical sexual response cycle includes four stages:

- Plateau: Heightened arousal with intensified physical responses.
- Orgasm: Peak of sexual pleasure marked by rhythmic contractions and release of sexual tension.
- Resolution: Body returns to a resting state, with men experiencing a refractory period where they cannot immediately orgasm again.
Understanding this cycle can help individuals and couples better navigate their sexual experiences.
