A good post Jeanne- it's well worth noting that while there may appear to be superflous subs & not so many desireable Doms, it's not a whole lot easier to find the right sub either.
If lisa finds a live-in position as I hope she will one day, I have no idea whether I'd even look for another formal D/s relationship.
Believe me, not all subs are up to the task either.
There's nothing trite about 'The One' turning up unexpectedly- that's very often how it happens.
