Interesting how a thread started and what it evolved into.
It started by suggesting that it might be necessary to employ some silly ruse to "compensate" for the "lack" of a wedding ring.
It quickly evolved into a discussion of negiah and yichud.
My conclusion... the chachamim understood human psychology real well. If a ring would do the trick, they would have come up with that one. They came up with stuff that really works. And yes, the chachamim even understood the psychology of all those loose women who the members of this forum claim are throwing themselves at them all the time.
