If I may add to the debate - from a non-expert perspetive i hasten to add -
it appears to me that the element of control in a rape situation is instantaneous and gives a feeling of power over the victim, which is the resultant sensation that the rapist needs in order to satisfy his craving.
the element of control with a paedophile victim is more subtle, and takes longer to acheive, with a degree of subtlety and skill which as virtually the opposite of the instant reaction in a rape.
It would appear to me that for a paedophile, control through grooming will lead to an aquescent victim, which adds to the illusion that the victim is a willing participant in the abuse, thus allowing the paedophile to pretend complicity as a rebuttal to any notion of coersion.
For a rapist, the opposite is true - the instant and violent assault is in itself the purpose of the action, the only control required is the fear of the victim which rsults in submission.
Having considered it, I think that an aspect of 'control' exists in both cases, although as is often the case when trying to decipher deeply complex deviant behaviours, the limits of our language mean that the term 'control' has to be the catch-all term for both situations, which is not ideal, but it is the word that best describes the scenarios i have outlined.
i await the responses from my fellow posters with great interest...
