Gender Vs. Sex
Gender and sex are two very different things. Sex pertains to the sexual organs you may possess. Gender is what you are mentally and sometimes causes you to feel uncomfortable with the body you were born with. It is important to respect others and don't just judge a person because they may visually look female or male. It is always good to ask someone what pronouns they go and call them by those.
