Girl crushes... EVERYONE HAS THEM. They pretty much mean absolutely nothing. You have time to figure out what you are. BTW, I am more fond of girls relationship wise than boys too. I don't know why, but it doesn't phase me. If people are pressuring you to go out with someone, just tell them one of the common go away phrases of today! And if they want to know who you like, make it up. Dating isn't everything. And my #1 life experience quote is... LOVE SUCKS.
I don't think that means a lot! Maybe it's just about your likes because everyone has different likes so I can't judge you on that basis!
And as one anonymous answered your question, for that I would like to just give my opinion that yeah relationship or friendship or whatever with a girl is nice as well, but still I like relationships with boys more because they make me feel special and all the boys I've met till now haven't ever broken my trust and they have been so caring towards me but most of the girls I've met they are always jealous, rude and mean towards me but till I've met girls who are my greatest friends! So I'd just like to advise that for good company, to laugh, share tell your fears and be frank with go to girls, and to love, feel special, feel alive, and to get the one who cares for and understand you the most go to boys! That's all that I feel!
The traditional definition for someone who is attracted to both females and males is bisexual. So yes, most people would consider a female who is attracted to men and women as bisexual (bi- is a suffix which means "two").
It's important to remember, however, that you don't need to allow people to pigeon hole 'what you are' with definitions.
Just be YOU
There really is no need to categorise yourself as one thing or another in this day and age. Some people will be attracted to the opposite sex, some people will be attracted to the same sex, and others will be attracted to both.
There's nothing weird about any of those attractions, and if people want to label you as this or that, then it's their problem, not yours. Some people's attractions also change as they grow older, so just because you're attracted to males and females at one point in your life, it doesn't mean you always will. Either way, it doesn't matter whether you're 'bisexual' or not, as long as you're YOU.
