性传播疾病的预防：行为的改变
STD Prevention: Behavior Change

节欲-节欲的各种含义

实际上，术语“性节制”可以有多种解释：

1. 节制所有的性活动（包括自我性刺激）。
2. 节制所有的性接触。
3. 节制插入式性接触（口交、肛门性交和阴道性交）。
4. 节制阴道性交。
5. 在某些时候和某些情形下节制阴道性交。

当在讨论AIDS预防的时候，在宗教领袖和卫生保健专业人员的脑海里，常常只有上述解释中的前2条或前3条概念。狭义的节制（第4和第5条）通常只有在个人咨询和治疗的案例中才成为议题。

9-12年级（15-18岁）学生性交统计
图表显示有性交行为学生的百分比。虽然百分比已经随年而有所下降，但是其中一些学生有4个或更多的性伴（柱形图的深色部分）（百分比按年分布：女生为52%-43%之间；男生在56%-48%之间），仍然持续超过40%。有4个或更多性伴的青少年的百分比仍然维持相对较高（女生：为15%-11%；男生：是22%-17%）。

The graph illustrates the percentage of students who had sexual intercourse. Of these, some had four or more partners (darker parts of the columns). While the numbers have decreased somewhat over the years(Range: F. between ca. 52% and ca. 43%; M. between ca. 56% and ca. 48%), they have remained at over 40 percent. The percentage of adolescents with four or more sexual partners has remained relatively high(F: between ca. 15% and ca. 11%; M: between ca. 22% and ca. 17%).

Abstinence - Different Meanings of Abstinence

Actually, the term “sexual abstinence” can have several meanings:

1. Abstinence from all sexual activity (including self-stimulation).
2. Abstinence from all sexual contact.
3. Abstinence from penetrating sexual contact (oral, anal, vaginal intercourse).
4. Abstinence from vaginal intercourse.
5. Abstinence from vaginal intercourse at certain times and in certain cases and situations.

When discussing AIDS prevention, religious leaders and health professionals often have only the first two or three of these meanings in mind. Abstinence in the narrower sense (4 and 5) is usually an issue only in cases of individual counseling and therapy.
