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

For me its about connection. Sometimes I'm very connected to being a girl - I like to be feminine and wear dresses and make up. Sometimes I'm very disconnected from being a girl, but I don't feel like a boy either. For me its what gender I do/don't connect with and how comfortable I feel with that gender.

Well, you can only do a bit of self-examination. You have to think about how you feel and then you have got an answer. Anyways, gender is a very weird concept, so it's okay if you aren't entirely sure what's yours.

Go to a shop and just allow yourself to go to clothes that you find comfortable and that you want to wear. Don't just look between your legs. Look at you and at who you want to be.

What's most important is what makes you feel most comfortable. If others disapprove with your decision, it's may be a good idea to schedule a therapy session with those who are confused with your decision to help them understand the way you are feeling!

It's difficult to make guesses, especially through online chat. It's best to ask someone directly about how they would want to identify themselves.

When it comes down to it, you need to find what you feel comfortable identifying as. If the idea of being male feels the most comfortable, then that might be your answer. The same goes for female. Your anatomy doesn't define you. If you are born a male but you feel most comfortable as a female, or vise versa, then there you go. If you feel more comfortable as a female than a male in some situations but more comfortable as a male than female in others, its possible that you are gender fluid. There's always agender if you don't think that any gender lable fits you. Gender identity may be a big part of today's society in some ways but you don't have to make it a big deal if its not that important to you. Try your best to love yourself for who you are. No matter what makes you different or marks you out.

I think you just get a sort've tug in your heart, you know what makes you comfortable and what doesn't. Discovering your gender is tough, some people know when they're very young, others don't until they're seniors. Sometimes finding a community of people also questioning their gender is a great way to help discover your own. It's not always easy figuring out how you fit into the spectrum of things. Finding a community of people, people who I am still great friends with, helped me to come to terms with who I am, and we have grown together. Finding people who also are faced with the question of "What am I?" is tremendously helpful, and it's comforting to know they also struggle with things like gender dysphoria, and coming out. I think a great way to discover who you are is to perhaps try out different pronouns, maybe he, she, or they, and accompany it with perhaps a different name, or the same name. Have people use your new pronouns, or try one of the many websites that allow you to hear yourself spoken about with different pronouns, and you can see what really feels right and comfortable for you. Being trans is a journey, not always an easy one, but one that's worth it in the end. I'm always eager to speak about trans issues.

It's not always that easy to know, it can take years until you're completely sure. You might have to keep out what others label you as, and really look into yourself. You can also search on the internet and see what gender you feel fits you the best. But of course you can "change your mind" if you later feel like it doesn't fit you properly.

Well gender in general is a social construct and means certain roles, behaviors and looks associated with one gender. As you stated, there are more than two genders and it's also a lot of what is accepted in your country. You can know which one you are by which one you identify the most. There are also a-genders which basically don't see themselves as a specific gender or doesn't believe in the gender construct at all. It's a lot about your inner feeling and how you see yourself the most comfortable,

You shouldn't have to force yourself into an identity. Whatever you're comfortable with, you should go along with that. Scientifically, being able to tell if you're a boy or a girl should be easy. But personally, you have your doubts and questions on what you really are. What ever you feel more comfortable being, whether thats being a boy, a girl or something else entirely - go with it.
