What type of consent requires active agreement from both partners?

Affirmative consent is the correct choice as it specifically requires active, voluntary agreement from both partners to engage in any sexual activity. This means that both individuals must expressly communicate their willingness to participate, ensuring that consent is clear and given without any ambiguity. This form of consent emphasizes that silence or lack of resistance does not equate to agreement, and it actively promotes the idea that both parties should engage in open communication regarding their intentions.

In contrast, other types of consent do not necessitate this level of proactive engagement. Implied consent occurs when an individual's actions suggest agreement, often without verbal confirmation, while passive consent typically refers to situations where one partner does not object, leading to assumptions about consent. Informed consent involves ensuring that one party understands what they are consenting to, which is often used in medical or legal contexts, rather than in the interpersonal context implied here.
