Steeltoe,
I'll answer you, never. I never had a choice either, nobody does, not about this feeling - only a choice, as you have already pointed out, to act on a feeling, any feeling.
I dare say that few will answer this honestly, lest they are prepared to defend it, and it can be a challenging point to defend. Almost as difficult as it would be to convince someone that you have a choice about how tall you are, or how often you blink your eyes.
