性反應
在人類，男（藍色曲線）女（紅色曲線）的性反應都遵循著相同的基本反應模式：A
=興奮期；B
=平臺期；C
=高潮期；D
=消退期。可是，女性的性反應模式中，存在某種可能的變化，例如，多次性高潮反應。
Sexual Response
In humans, the sexual response follows the same basic pattern in both males (blue) and females (red): A = Excitement, B = Plateau, C = Orgasm, D = Resolution. However, there are some possible variations in the female pattern, e.g. multiple orgasms.

術語“性行為（sexual
behavior）”可以是指涉及到身體“性反應”的任何行為。
這是一個現代的和頗為注重實效的定義。這個定義表明，當動物交配的時候，有許多都會經歷一種必然的生理改變，這種生理改變顯示一種特徵性的反應模式，被人以術語“性反應（sexual
response）”將其做了概括。有人進一步注意到性反應甚至在生殖不可能發生的情況下也可以發生。因而，人們發現一些動物獨處的時候卻正在刺激它們自己的性器官，或者正騎跨在屬於它們自己性別的夥伴背上，或者正設法與其他動物物種（包括人類）的個體發生交尾行為。在所有的這些行為裏，都可以發生顯而易見的性反應。這就是狹義定義的性行為。在人類，這種不導致生殖卻涉及性反應的行為也常被稱作性欲行為（erotic
behavior）。
Introduction - What is sexual behavior?
Current Meanings of the Term 2: Erotic Behavior
The term "erotic behavior" can refer to any behavior involving a "sexual response" of the body.
This is a modern and rather pragmatic definition. It reflects the observation that, when they mate, many animals experience certain physical changes which show a characteristic pattern and which may be summarized in the term "sexual response". It has further been noticed that this response can occur even in situations where reproduction is impossible. Thus, some animals have been seen stimulating their own sex organs when alone, or mounting partners of their own sex, or trying to copulate with members of other species (including man). In all of these cases, an obvious sexual response is involved. This is sexual behavior in the narrow sense of the term. In the case of humans, it is also often called erotic behavior.
