An office is a tricky place for such an alliance even if you were single...Especially when the sub in consideration is your subordinate...If and when things get messy[as all relationships do], some of it will inevitably spill over into the workplace....And seeing how our lifestyle is still sub-tabard in a world that accepts many others more openly....Well...the cons outweight the pros unless you are open about it already.

Considering the fact that you are already content with your sub, It should not be too hard to distance yourself from the 'temptation' at the workplace...the more you draw back, the more he will too if he gets the hint...Hope the issue settles for you.

Blessed be,
