Think about if you would kiss a guy or girl or both. And I am lesbian and have never had a crush on a guy, or anyone really for that matter, well, maybe one girl, but put that aside. But here is this thing, you don't have to be anything. And if you don't like questioning, you can use the word queer if it suits you better, cause queer just means "not straight", it is not specific. And I have not been in a relationship too, and yet I am lesbian still, cause I like girls that way and would puke thinking about guys that way lol. But don't put to much pressure on it, and if you really want something to define yourself as, take a few online quizzes (though, don't trust them too much).
