 Perhaps fantasies are a better guide if we have a good way of distinguishing between fantasies that indicate the person’s sexual orientation and those that don’t (after all, David’s desire for Tom is a fantasy of sorts; Storms 1980). This might push us to ideal conditions again, to distinguish between someone’s real and “fake” fantasies. Or we might rely on initial sexual impulses: what sexually catches the eye of someone, without much thought: David does desire Tom’s oral skills, but what captures David’s sexual eye are women, not men.
