How to answer questions about your sexual orientation

As an aside, I cannot refrain from relating another anecdote, which is told of Gore Vidal.  In a TV interview he was asked: "Was your first sexual experience with a man or with a woman?"  To which he replied: "I was too polite to ask."

That is from Žižek citing Dolar, p.121.  It's a shame that Kagan does not have the liberty to answer in the same manner.
