Those situations are more edge cases and they are quite difficult because knowing what we know about the mind, it can play tricks.  For example, we may feel very happy at one moment, but something could transpire to change the feeling and that may cause us to retroactively view the initial consent (maybe they thought the person was initially someone else) in a different light --but at the same time, most people give the benefit of the doubt internally (that is, even if they are truly aggrieved, they are likely to interpret the violation as their own fault, rather than blame the perp)  It can become murky.<p>To make the point less gender political, view this as something which happens to a same-sex couple, so that the dynamics are less obvious about sexual politics and more about either force, misinterpretation, misrepresentation or confusion or a mixture of all the above.
