I have known several “confirmed bachelors” over the years and they most assuredly were not gay. One was a workaholic, a scientist, who was devoted to the work he did. I have thought of him as one who married his job.
that’s interesting
i’ve known a few also...but in retrospect, I think they were “sort of” gay, though not really active as it were.
i do think that a scientist could fall into the asexual category because of the nature of that work....
