This paper establishes what constitutes a sexual interaction between two or more people. It does this by first defining a sexual activity as one in which the agent intends to satisfy a sexual desire. To understand what it means to engage in a sexual activity with another person, it draws from Bratman’s account of shared collaborative activity. A sexual interaction is defined as one in which two or more people engage in a sexual activity together, with the intention of satisfying (...) a sexual desire in a mutually responsive and mutually supportive way. The paper then uses this account to consider what things constitute sexual infidelity. The answer is a broad one: many things can count as sexual interactions and hence can be considered to be sexual infidelity. Contrary to what a lot of people think, this can include the private use of pornography. (shrink)

This article uses a notorious incident within the computer program EVE Online to exemplify and facilitate discussion of the metaphysics of virtual worlds and the morality of user behavior. The first section examines various frameworks used to understand virtual worlds, and emphasizes those which recognize virtual worlds as legal contracts, as representational worlds, and as media for communication. The second section draws on these frameworks to analyze issues of virtual theft and virtual betrayal arising in the EVE incident. The article (...) concludes by arguing that, in the absence of countervailing contractual obligations, users of virtual worlds have the same de facto duties to each other as they do in mediated and real environments.
