Years ago, people were constantly questioning my gender, because I presented myself as extremely androgynous.
My cousin, who was four at the time, was even extremely confused by my appearance and was unable to properly gender me. He actually didn't know if I was a "he" or a "she" up until then. Unfortunately, this was before I came out as trans, but I still knew I was, so the situation was extremely dysphoria inducing. However, causing public inquiry had its perks. Oddly enough I was read as male sometimes even then though by stranger - even people who attempted to sexually pursue me; I didn't bind at the time, and merely hid under layers and layers of clothing. Still my buxom chest was ultimately the give away - I did sound like a girl when I spoke, but some people seemed to totally disregard that. For some reason, Asians always seemed to read me as male 100% of the time, even when I was andro. Kind of a weird thing that I noticed.
