If I made it seem as though I distrust your testimonial I am sorry for the misunderstanding. I am trying to agree that this is entirely possible and doesn't surprise me in the least.
I would agree that most scholars do not provide an accurate assessment, but I believe the Kinsey Scale has some value to this particular conversation. If only to point out that these categories we want to put each other in are not helpful.
If I may give my own personal testimonial, after I had come out as gay, a few years later, I slept with a man. Holy crap! Did i ever get shit from the straight people in my life! I seriously lost a few friends who I had never had any romantic involvement with. I was told by one angry male friend that he felt 'betrayed' because I had told him I was gay. I
am gay. There is no lie being told there(and I don't understand how who I have sex with effects someone I have absolutely no romantic involvement with anyway). My point is that regardless of why or who, people are
determined to put people in a box and in my experience they generally become angry or frustrated they can't easily do that or their views are challenged.
Think about the social climate for a young male who is just discovering his sexuality. I use a male in this example just because our culture is much more forgiving on gay females(for entirely unique sexist reasons). Think of all the gay slurs, etc. thrown around by the common teenage male. Any small feelings of gay sexuality may signify to a young guy that he is completely gay. He may not be, he may be bisexual, he may be mostly straight with a few gay tendencies, but to his peer group 'a little gay' means all gay. His choices in sexuality as he perceives them are gay, straight or bi and nothing in between. So the young male thinks he is gay because he got a boner looking at a men's health magazine. He knows if he told anyone in his peer group, they would immediately put him in the gay category. So he wrestles with his thoughts and finally comes to grips with his gayness and comes out. It may not be until he is far more mature that he realizes he doesn't have to choose one or the other, or that he was perhaps hasty in labeling himself anything in the first place.
In terms of the relationship between your report and the truth, another interesting aspect is that the truth as your report relays, is speaking about a human being. A creature who's 'personal truth' is malleable and in constant flux. Whether your report rings true to it's subject could vary from minute to minute.
Ah a quick re-read has lead me to the conclusion that I have rambled thoughts that may or may not be of any interest to you. I was going somewhere with this, but several phone call interruptions have derailed me. But now that I have written it. It stays. My apologies.
