Thank-you for the clarification, Professor Coulson.

From what I'm understanding, questions regarding sexual issues are considered improper, but is that true of all bodily functions? How do you know which questions are considered improper and which ones aren't?

In any case, I think I'm probably going to follow Professor Mercer's advice and do research elsewhere. I think I might be more confused now than I was when we started the discussion, so a different sort of research might be for the best.
