Maybe this opinion slightly misinformed but - over the years of slaying biznatches - perhaps it's only really, "dirty" (not the good kind) - for those that just aren't really sexual.
That is to say - when they're really hot - shit that normally seems disgusting - when they do it, it almost ADDS to the hotness.
Maybe that handjob brothel only SEEMED repulsive - cause the women working there were basically - not attractive?
Well - not necessarily not attractive just - not hot.
They didn't raise my pulse.
