I recognize that there are two genders depending on the chromosomes. However, genders are not something that is binary. Some people tend to be mostly male, or mostly female. There are people who are in-between, and there are worse situations when someone has chromosomes who made them develop a female body, but they also act and feel male. The opposite condition is also awkward.

My owner... He's undergoing a gender change. He doesn't feel comfortable as being a man in real life, and I can't really share all the motives, emotions and explanations as they are too intimate to share, but know this; gender is not something easily understood, nor it develops perfectly for everyone.
