Gender identity. Why so much confusion?

Look the point of this post isn't meant to offend anyone who is part of the LGBTQ community. I simply want to understand the logic and reasoning behind why someone would be confused about their gender. Again I'm not trying to attack anyone but to simply increase my knowledge and understanding of why people choose a different route in life. How exactly can someone "feel" that they're actually a boy rather than a girl vice versa. Not to mention where did terms such as "demiboy" or "demigirl" come from? How can you "practically" connect to another gender? I don't know I'm sorry. This confusion is confusing me. Let me know what you think.
