This reminded me of a couple interesting fetish-type activities that some hetero guys participate in which allow them to have man-to-man sex, but still call themselves straight.
Westla, I agree, even if I wouldn’t label them as completely straight (following your speech and generally speaking, after analyzing an average/common man’s whole life, maybe genuine “0” value guys could be utterly nonexistent or rare ;) )
Furthermore, if I remember well, Kinsey’s scale was conceived thinking to virtually intermediate values not only rigorous and predefined ones (so that only 0 and 6 are really fixed, and there are almost endless undertones): indeed we can have a guy positioned at e.g. 0.5, 1.2, 2.6, 3.4, 4.1, 5.8 and so on.
Answering Monument, technically, a guy who masturbate someone else (male) could have any value (maybe) less than 3 and surely always more than 0.
But we don’t necessarily have to fossilize ourselves on this topic, they are only raw numbers :P
