It’s a favorite date question, though not one that should be used in the first half hour to forty minutes. Unless you have a freaky yes-girl. It can be used as an hour-long, first-date spike, sprinkled amid non-sexual topics.
Often it should be framed as, “Tell me about the last time you were tied up.”
Notice the phrasing: “When was the last time” or “Tell me about the last time” assumes that it’s happened before and that it’s normal. As opposed to, “Have you ever been tied up before?”
I should make a list of favorite date questions and pseudo-questions. I never have, but many of them recur. “Tell me about your peak experiences” is another.
If the chick says she’s never been tied up, look at her quizzically and pityingly and say, “That’s weird. Never? How old are you again?”
I think this (usually) works for me because it starts to make her qualify to me, and if she says she’s never done it, she gets to thinking about why she never has. Does she not inspire enough lust and creativity in men? Is it something else? Has she always dated inexperienced losers?
Or do I just like freaky yes-girls?
I know less about why things work than that they (sometimes) work.
