One major difference between the sexes is the range of variations in the sexual response cycle. Although the graphs in Figures 6.3 and 6.4 do not reflect individual differences, they do demonstrate a wider range in the female response. One pattern is outlined for the male, and three patterns are drawn for the female.
In the female chart the sexual response pattern represented by line A is most similar to the male pattern (see Figure 6.3). It differs in an important way, however, in its potential for additional orgasms without dropping below the plateau level. Line B represents quite a different female pattern: a smooth advance through excitement to the level of plateau, where the responding woman may remain for some time without experiencing orgasm. The consequent resolution phase is more drawn out. Line C portrays a rapid rise in excitement, followed by one intense orgasm and a quick resolution.
Although it appears that women often have more variable sexual response patterns than men have, this does not imply that all males experience the response cycle in exactly the same way. Men report considerable variation from the Masters and Johnson standard, including several mild orgasmic peaks followed by ejaculation, prolonged pelvic contractions after the expulsion of semen, and extended periods of intense excitement before ejaculation that feel like one long orgasm (Zilbergeld, 1978). In other words, there is no single pattern of sexual response, nor is there one "correct way." All patterns and variations—including one person’s different reactions to sexual stimuli at different times or in different situations—are completely normal.
Are the sexual behaviors and attitudes of women more variable (erotically plastic) than those of men and thus more susceptible to the influence of sociocultural factors? A study of college women and men that addressed this question did not find evidence supporting the view that women are more erotically plastic than men (Benuto & Meana, 2008).
