异性肛交的原因 |
|
异性肛交尽管不普遍，但并不比人们所认为的那样罕见。按照参与者的文化背景不同，他们进行异性肛交主要有三个原因：
|
|
|
-
①
保持女子的“童真”；
-
② 避免怀孕；
-
③ 为了变换性爱花样。
|
|
|
当然，这些原因也以复合的情况出现。
-
第一个原因可能对生活在许多“传统”社会的性伴适用，在那里会谴责未婚者之间的性交。这样的社会强调女子带着未破裂的处女膜结婚，证明她们在性的方面是未被触碰的和“清白的”。至于未婚者的肛交则是一种容易理解的选择。
-
第二个原因可能在不容易得到避孕药具的社会或情形下可能成为主流。在这种情况下，性伴双方把肛交当作性交的一种替代选择。
-
第三个原因可能对变着花样做爱的性伴具有吸引力，他们喜欢体验许多可能的身体亲昵行为方式。

2. Heterosexual Intercourse: Anal Intercourse
|
|
Reasons for Anal Intercourse
|
|
Heterosexual anal intercourse, while not common, is not as rare as is often believed. Depending on the cultural background of the participants, it is practiced for three main reasons:
|
|
|
|
1. To preserve the female’s “virginity”,
2. to avoid pregnancy,
3. for the sake of erotic variety.
|
|
|
|
These reasons may, of course, also be present in combination.
- The first reason is likely to decisive for couples in many “traditional” societies that condemn sexual intercourse between unmarried partners. Such societies may insist that females enter marriage with an unbroken hymen as proof that they are sexually untouched and “innocent”. For unmarried couples anal intercourse is one obvious alternative.
- The second reason is likely to predominate in societies or situations where contraceptives are unavailable. In this case, a couple may regard anal intercourse as an alternative to coitus, because it cannot cause pregnancy.
- The third reason may appeal to couples who vary their lovemaking and who like to experiment with many possible forms of physical intimacy.
