In Russian, when communicating, it is usually clear who you are (or who you prefer to be). I use my real photo on social networks. But even so, sometimes I was taken for a guy. They wrote me, that I am a gay who disguises as a girl. By the way, in the photo I was in a dress. Probably, they thought that the girl could not talk on the topics of transhumanism or artificial intelligence.
And in real life I was often mistaken for a boy or a guy. I just prefer pants and jeans. I like heavy boots. And I don't use make up. Because of this, my husband's mother does not consider me a normal woman. 
My drawing style is close to anime. Therefore, male characters can sometimes look too feminine.
