 (3) A supererogatory action is permissible but not obligatory, is intended to benefit the recipient, involves, or probably involves, “a significant reduction in the interests or good of the agent, [o]r the act is risky, significantly, not trivially”, and is such that the agent knows or truly believes this in advance (Soble 2017a: 452; the agent’s belief has to be true; falsely believing that the act is risky might disqualify the act from being supererogatory). There can easily be permissible, non-obligatory sexual actions intended to benefit the recipient. So everything hinges on the criterion of serious risk to the agent.
