How can you tell if you are a boy or a girl, or something else entirely?

It can be as easy as looking at a list of genders and seeing what fits or as hard as deeply contemplating and figuring out how you feel inside, basically you just need to be informed of your options. And not many people know their options.

Be yourself. Dress the way that makes you happy, do the things that make you happy. Worry about labels later. The answers may not come as soon as you want them to, but they will come in time.

Anatomy is not always a way to tell what gender you are. Go by your personality, what you like most and if deep down you feel more like a girl or a boy :) You may feel like you are both and that is okay :)

Gender does not equate to biological sex. This being said, you can tell if you are a boy, girl, or something else just by what you feel you are; what you identify as.

This question has multiple possible answers. If you're looking to look into this yourself about yourself, you could try some quizzes that help you look into who you may be.

You can tell if you're a boy or a girl or something else, by taking a second to really feel, and look in the mirror, and just think of what makes you happy. You don't have to have any labels, just be YOU. Whatever feels right.

I personally am not 100% boy or 100% girl. I believe most people have alot of personality traits, male and female and more. Its like an army of Males, Females, Robots, Pets, and Energy-beings inside every Person. And thats why it would be weird to claim to be 100% male. then again maybe thats just me. also i think everyone has a "major me" (or "major you") which is the main ... charackter if you so like. And if thats male than its likely that you will define yourself as mostly male. I dont know if you can really tell for sure... i guess you just "know" at some point what fits best if anything.

Well, since I'm genderfluid its all based on how you feel in my opinion. It might not be that way for others, though.

Gender is very subjective. I would say that it is unnecessary to identify as either if you don't feel like a man or a woman. Normally the defining attributes would be based upon how elegant or sturdy you feel you are, or if you tend to be more dominant or submissive. It is all very vague and stereotypical though, so it is difficult to truly define what a boy or a girl is. Nobody can tell you who you are better than yourself, so I think self-discovery is needed in order for you to understand.

Only yourself can tell that because you are you. No one else can tell you because your opinion is the best opinion.
