People asking you if your a girl or guy in your relationship.
I had someone come up and ask me "so if you were dating a guy, would you still be the girl in the relationship?"
No idea what the heck that person meant....
Are you asking if in a relationship with a guy I act like a girl? Uh yeah, because female is the gender I identify with!

I personally don't like people asking that question, it's just strange.
It's like asking. "SO WHOS THE PERSON IN THE RELATIONSHIP???"
Gender doesn't really matter to me... I mean, people can identify as male female, or even both.
So it's kinda pointless to ask who's the girl and who's the guy because all you're talking about is the stereotypical girl/guy in a relationship.
So really those stereotypes could not even fit the mold of the couple you're asking the question to.
