People who typically say "don't worry about labels!" tend to be straight, so don't feel bad if you want a label that will help you understand yourself and your relations/feelings towards others. It's perfectly normal, and is a good tool when learning about yourself and meeting others.

Bisexual does not have to mean you're attracted to men and women equally. You can be far more interested in perusing a relationship with a female and still find boys cute sometimes or even date them in the future. I think people get stuck when they identify this way because we are taught that bisexual people feel a 50/50 split in attraction. That is simply untrue.

Any sexual orientation that is not heterosexual can be called queer by a queer person, btw! And it can be used for people who don't fit into the binary system of sexuality.
