in a fantasy world??? in a fantasy world i would wish to be completely restrained, stripped to the waist then flogged mercilessly, to the point that my entire back was gushing with blood and i would pass out from the loss of blood...but for obvious reasons thats never going to happen in reality (totally unsafe starters!!!)...was that the kind of thing you were looking for???
i do have other fantasies at other times, but thats the one that popped into my head right now...
and i think preferences about marks after a session are a matter of personal opinion...i know i love having marks (bruises etc.) as a reminder of what we've done...especially bruises that i can still feel for days afterwards...
