What is the definition of abstinence in the context of sexual health?

Abstinence in the context of sexual health is defined as not engaging in sexual intercourse, which effectively prevents both pregnancy and the transmission of sexually transmitted infections (STIs). This choice encapsulates the essential premise of abstinence, highlighting that by choosing not to have sex, individuals can avoid the potential consequences associated with sexual activity, such as unplanned pregnancies and health risks linked to STIs.

The other choices either do not fully capture the idea of abstinence or describe different concepts related to sexual health and relationships. For instance, one option mentions avoiding physical relationships, which may imply other forms of intimacy that are not strictly sexual. Another suggests the use of contraceptives, which directly contradicts the concept of abstinence. Lastly, delaying sexual activity until marriage suggests a specific context or viewpoint on abstinence rather than addressing the broader definition that encompasses any period of refraining from sexual intercourse, regardless of marital status.
