What sort of “causes” have you heard or thought up for you being ace and/or aro?
One possible cause, kindly suggested by a relative, was that I went to an all-boys high school, and thus did not have a chance to develop an attraction to women during my formative years.
He didn’t really need to make the suggestion, because I already thought of that hypothesis on my own. But it doesn’t make any sense, because for most of my peers, their “formative years” were in middle school. Also, I was not attracted to men in high school even though I am now. Also, I have literally never heard from another ace who made a connection to an all-boys or all-girls high school.
