Two Types of Erogenous Zones in the Skin
nonspecific type
specific type
erogenous zone:
- Similar to any other portion of the
usual haired skin
nonspecific type
erogenous zone:
- Nerves are composed of the density of dermal-nerve and hair-follicle networks
nonspecific type
erogenous zone:
- An exaggerated form of tickle
nonspecific type

Includes the sides and back of the
neck, axilla (armpits, underarm),

sexual response cycle
Sexual Response Cycle (Masters and Johnson) 4 phases:
- excitement
- plateau
- orgasm
- resolution
- Initial physiological sexual arousal response
- Increased heart rate, respiration, and blood
pressure - Myotonia, vasocongestion, and nipple hardening or
erection - Flush or reddening of the skin
phase 1: excitement
- Intensifies the response from the excitement phase
- Continuous increase and stabilization of breathing,
blood flow, and heart rate
phase 2: plateau
- Sexual climax of excitement
- Shortest and generally last only for a few seconds
- A sense of euphoria and a feeling of tension relief
phase 3: orgasm
- The body returns to its normal functioning
- Refractory period – the recovery time after
orgasm.

the recovery time after
orgasm
refractory period

brain
- Translates nerve impulses sensed by the skin to pleasurable sensation
- Controls the nerves and muscles used in sexual activities
- Releases hormones (physiological origin of
sexual desire)
brain
responsible for sexual
thoughts and fantasies
cerebral cortex
the source of emotions and
feelings
limbic system
“love hormone”; desire to
maintain close relationships
oxytocin
hormone for ovulation in females
follicle-stimulating hormones (FSH)
regulates the testes and ovaries; stimulates the production of testosterone from the testes
luteinizing hormone (LH)
