FIGURE 11.2 • The Human Sexual Response Cycle According to Masters and Johnson (1966), during the normal sexual response cycle, women and men go through four stages: excitement, plateau, orgasm, and resolution. However, women can experience multiple orgasms without a refractory period (a), whereas men must experience a refractory period before a subsequent orgasm (b).
