按照特定時間、特定的環境和情形，性的3個層面是相互獨立的和相互有差異的。因而，這3個性的層面塑造了每一個個體的性文本。

這個性文本還包括他的或她的性興趣或性偏好。但是，性偏好並不必定是永久的，它可能會在一生中發生改變，不是自然發生改變就是因為積極或消極體驗的結果而發生改變，或者因治療的結果而發生改變。另一方面，性的某些方面是不可改變的（例如：性染色體）或能夠證實有條件地發生改變（例如：性自認和性取向）。

The three basic aspects of sex are independent of each other and interact differently according to particular times, environments and situations. Thus, they shape each person’s individual sexual profile.

This also includes his or her particular sexual interests or preferences. However, the latter are not necessarily permanent. They may change in the course of life, either spontaneously or as a result of positive or negative experiences, or as a result of therapy. On the other hand, certain aspects of sex are unchangeable (e.g. chromosomal sex) or can prove to be resistant to change (e.g. sexual self-identification and sexual orientation).
