In 1967, as a soon to be graduate from a university in what is today called computer science, I applied to the NSA and nothing about that interview was nice. I failed the polygraph on two consecutive days and that's all she wrote. What tripped me up was the question "have you had any homosexual activity." The pen almost went off the graph when I truthfully said, "no."
Where and when I grew up that was about the worst thing that could be said of a young male. On the trip to the interview my magic magnifying mind had wondered about whether sensitivity to a question alone could cause truth to appear to be a lie. Of course the question that popped into my mind which I anticipated was the question on homosexual activity. Well, having thought about it beforehand, sure enough I reacted strongly. It was just as well because the overall interview had shown me that I didn't want to work there anyway but it was still traumatic to be accused of lying and about that in particular at that time.
For a short period of time I questioned my sexuality but can say that in the intervening 51 years there has not been one moment when I considered homosexual behavior. This is not to say anything negative about homosexuality, just how one's fear of responding to a question can cause one to respond negatively even with a truthful answer.
Times were different then and my attitude was too. I doubt I'd fear the question today given that my accepting attitude toward homosexuality in general has been normalized.
