After being a professor for a number of years, this topic has a different meaning to me than maybe you.
Before you think the question is dumb, think of the possibility that you did not make it clear enough such that the question was asked.
So, the worse question comes at the wrong time as, "Are you sure I can't get pregnant with this?"
Dumb relates to, "Is it real?"
And most damaging, "Honey, does this dress make me look fat?"
