The calculation (1.96 / 2) / sqrt(164) for the margin of error isn't applicable in this case because it's not a Bernoulli pass/fail event, and is instead an open-ended question.
If you framed the question as "Do you think this is a sex object? Yes/No" then the margin of error might be more applicable. I count 10/164 (6%) who did: stating that 94% of people don't think AirBNB's logo is a sex object is a much better lede.
