Now you're asking the right questions even though you meant them rhetorically! First, it is an obvious and banal statement that "conversations can begin any number of ways." I prefer they begin honestly, and not deceptively, so people are clear on the question, enabling them to give meaningful answers. The issue with entering a conversation obliquely (extra credit to you for vocabulary) is the shadow of mendacity (I want vocab extra credit too!) and discredit it casts over the person asking the question. It is an invitation to not take the question, or the person asking the question, seriously. It is also an indication the poster is afraid to ask the question plainly; possibly because, once asked plainly, the erotic image conjured in the person's mind is no longer titillating, losing its carnal power amid too many mundane responses. In that case, an opaque question causes respondants to hunt for meaning, making various attempts to satisfy the question, each time providing a little jolt of pleasure to the poster for having teased others to come ever-so-close to the target, without ever putting their fingers on it. As "Arbiter of All Things," that is my ruling.
