If one day I woke up and unexpectedly found myself in a monogamous marriage where I can tickle neither my wife, nor anybody else, I think I would run like hell.
However, had I for some reason consciously entered such a marriage after unsuccessfully attempting to (a) negotiate some sort of open relationship, (b) convince her to give hypnotherapy a try, (c) search for another prospective lifemate, and (d) convince her to allow me some non-interactive outlet such as tickling videos, I would have no choice left but to get the hell over it.
