Have you heard of Capgras syndrome? For people who have this (according to Wikipedia), “their conscious ability to recognize faces was intact, but they might have damage to the system that produces the automatic emotional arousal to familiar faces. This might lead to the experience of recognizing someone while feeling something was not “quite right” about them.” Possibly similar?

I didn’t select my friends from (a conservative Christian) college for lgbt-friendliness or non-conformist dating styles or really anything at all, besides maybe an enjoyment of genre television or some connection to friends I already had. And yet it turned out that at least a third of the women in my social circle share my love of hot bi guys and m/m in general. Also, m/m fanservice for the benefit of female fans seems to be rather a common thing for hot young male celebrities to do in certain cultures, such as Japan.
