same. in all the years that i've been to cons (alamo city, austin, houston) never have i seen girls say or give a look of annoyance when taking pics or people taking 'creeper' pics of their asses.
hell many of them pose with their asses sticking out.
this whole thing about 'cosplay is not consent' was probably some ugly/sjw cosplay that didn't get any attention.
about the only thing i see more now of is cops walking around and more 'friends/family members' at the girls booth.
but since the beginning i've always asked if it was okay to put my arm around their waste, but most of the time they're the ones hugging and putting their hangs on my chest (or other guests) taking pics.
