<<..so by Sherlockian reduction...ease suggested by the other option.>>

I'm with Mav on this one. Either because she's married, or unmarried, or "experienced," or whatever other either you may think of, at a certain age -- let's call it 30 -- romance is no longer that thing once taken so lightly. The ambiguity of the definition you cited is, I think, the result of its deliberately salacious -- call it romantic -- formulation.

Anu's spell checker insists that where I wrote "salacious," I meant "salad." But I can assure you, I eat my salad dressed.
