It would depend with the manner that you like him with. If you are attracted to him sexually, then you would be considered bisexual, but if you just like him as a friend, no one would judge you in that.
It is possible to have a same-gender-crush without there being a sexual component to it. Just because you connect with this guy on a different level doesn't make you bisexual. It may simply mean that you have met a kindred spirit. Unless and until something of a sexual nature or feeling occurs, you are not bisexual.
There are so many different words today that are used to describe someones sexuality that it's getting ridiculous. You don't need to be called anything. You don't need to understand everything you feel. Its nobody's business what you do sexually except for the person you are with. Be with people you are attracted to and feel comfortable with. Love who you love. Be yourself. The rest doesn't matter.
I you're a teen, you're probably bi curious! Everyone has been there! They won't admit it but they've had thoughts! Some even acted on those thoughts! I think you're bi-curious! You can have a crush on a guy & be straight too you know!
Don't label yourself anyway! Does it matter? Just be who you are & let everyone else be dammed (spelled wrong on purpose)! You only live once but most importantly, you're only young once! You know what they say; dance like no ones looking Sing like no ones listening!
