>>1122937Yaoi enjoys massive popularity among female anime fans. Plenty of them dress up as male characters because (a) guys have less revealing costumes, (b) male characters tend to be cooler, and (c) they identify with the dudes in yaoi anyway since it's written for girls. You do the math.
My gf and I were cosplaying as male characters at one convention and a fairly nice, attractive, sane-looking young woman asked us to kiss for a photo. I closed my eyes for the kiss but opened them again when I heard screaming -- we'd pulled a crowd of twenty-plus fangirls in the few seconds since I'd closed my eyes and they were all snapping photos. Never again.
