1. 兴奋期 若干基本的观察结果  不仅男性而且女性也能够非常快地达到性唤起，而且某些女性在数分钟内可能体验一次或多次性高潮。事实上，有一些女性在开始性交后的15-30秒内就能达到性高潮。 但是，似乎在性唤起的第一阶段，女性比男性更容易分散注意力，而且比男性更多地依赖持续的身体刺激。鉴于此，许多女性在性交时比她们的男性性伴似乎需要较长的时间来达到性高潮。男性的性兴奋常常以心理因素得以持续和加强。 总的来看，女性不太容易仅由视觉和听觉产生性刺激，或不太容易由性幻想和性直觉获得性唤起。另一方面，通常，当女性能够集中注意力在她们喜爱的性刺激方式时（例如在手淫时），她会象男性一样快地达到性高潮。

The Response Cycle: An Observed Pattern, not a Norm

1. Excitement

Some general observations
Not only men but also women can become sexually aroused very suddenly, and some of them may experience one or more orgasms within a few minutes. As a matter of fact, there are women who reach orgasm fifteen to thirty seconds after they begin sexual intercourse.
It seems, however, that during the first stages of arousal women are more easily distracted than men and depend more on continued direct physical stimulation. For this reason, many females seem to need a longer time to reach orgasm during coitus than their male partners, whose excitement is often sustained and increased by psychological factors.
In general, females are less easily stimulated by mere sights and sounds, or by erotic fantasies and anticipations. On the other hand, when the average woman is able to concentrate on her preferred method of stimulation (during masturbation, for instance), she achieves orgasm just as quickly as the average man
