  8. Sexual Reponse
    Masters and Johnson
    Underlying processes
    • vasalcongestion: blood flow
    • myotonia: muscular contraction
  9. Masters and Johnson
    Male Response Cycle
    Excitement Phase
    • first indicator is erection
    • -speed determined by age, fatigue, drugs

    testes pull up toward body

    • -cremaster muscles do this function, and if extended creates blue balls effect

    testes continue to increase in size until they are 50-100% larger than normal

    heart rate and bp continue to rise
  11. Masters and Johnson
