I'm not sure that counting gay porn searches (example they gave in the article) is a reliable indicator of whether the seeker is gay. This may be TMI for HN but once in a while I (a straight male with zero attraction to men ever) have searched for and "enjoyed" gay porn. I was curious about this phenomenon and found many forum posts where straight guys say they've watched gay porn.
Might that mean that you are bi? I mean, if you like watching it you might enjoy doing it. If your first response to that suggestion was visceral, maybe you actually have some aversion to the idea that you are. It makes sense, the world is easier for straight people, but it might bear closer examination.
Likewise watching natgeo animals mating doesn't make someone a zoophiliac.
