I believe your absolutest position is incorrect, based on my own experience. I am a gay man who has never experienced a scintilla of sexual attraction towards a woman— despite trying quite hard at times to experience such attraction.

Research I have read holds out my experience as not uncommon, though probably not in a majority of experiences.

I'm not sure where you get your data, but I believe you must be at least somewhat misrepresenting it.

And at least in my own case, I know with certainty that you are wrong.
