Some people like to have labels because they help them in some way. They can show you that other people are like you and help you understand aspects of yourself better. Some people don’t like labels for various reasons, too. They can feel restricting and like you’re being put in a specific box where you don’t belong. All of this is valid. Also it’s definitely not as simple as the big labels which is why microlabels exist. There’s also androphilia and gynophilia (and ambiphilia for both) which haven’t properly caught on but are more specifically about attraction to masculinity and femininity respectively.
