But they probably grin wolfishly at you while they're doing the tickling. I recall an incident some 35 years ago now - God, that LONG?!! - during my first real experience of sustained physical intimacy, in which I had some feelings of doubt or mistrust of my partner, and every time her hand came in contact with a really sensitive area, I couldn't stand the tickling sensation, which seriously interfered with the point of the whole experience...

At some point, however, something in me paused and I remember thinking clearly to myself, "(name omitted) really is of great value to me," at which point, as by magic, the tickling completely disappeared, replaced with a feeling of warmth and pure pleasure at the same touch that had me involuntarily strggling to escape seconds earlier. I know that I recalled Koestler's analysis at the time, but whether it was before or after the unbidden thought came to me I no longer recall.
