Girls are no different from boys minus the fact that girls have two X chromosomes and boys have XY chromosomes. Talking to the people who think female and male are 2 different things. The functions that girls have and boys don't is having a uterus. That is only organ that girls have that boys don't the rest of the body has the same function as boys. You people in the in-between gender though can take this info as you please because I hope that you would know most things of both biological females and males. Also you may ask about our chests. All that they are are oversized chest meat that somehow produces nutrients. Also not all biological females are really violent on their period. I don't have heavy mood swing like some biological females do. Everyone is different and that is ok the only thing not so different is the human body structure. Also people need to stop saying girls don't poop because infact we do just like any human being does.
