Zayn’s always had Louis, and thought he always would. But, when high school starts and that all changes, he’s left with nothing but old memories and a damaged heart. (a growing up AU where Louis’ the boy next door, and Zayn’s hopelessly devoted)
The night feels like it moves quickly, melting away as they all get steadily drunker; Zayn watches the boys eat and laugh and shove each other around and feels suddenly very glad to be with them, incredibly lucky to have all of them to himself. Especially you..
Do you know what intersex is? There isn’t only “male” and “female” Sex consists of different parts 1.) genitals (penises or vaginas) 2.) gonads (testicles or ovaries) 3.) secondary sex characteristics (facial hair or boobs) 4.) chromosomes (XY or XX) Some people are born with these things all mixed up For example, someone might be born with a penis, ovaries, develop boobs, and have XY chromosomes So sorry to inform you of this, but you are wrong. Biologically, there are not “just two sexes”
