Meaning of Being Bisexual?

People who are physically and sexually attracted to both men and women usually identify themselves as bisexual. However, not everyone who has had feelings or experiences with both men and women describe themselves as bisexual.
Sometimes, people are happy to explore their sexuality, but will identify themselves as mainly straight, gay or lesbian, or have no label at all. Other times, it can be hard for people to come out as bisexual because society doesn’t accept people who are attracted to both men and women.  For this reason, being bisexual can cause feelings of isolation for some young men and women, because they feel a lot of pressure to be either straight or gay. Some people find bisexuality hard to understand, but remember: there’s nothing “wrong” about feeling or being bisexual.
There are some people who find "bisexual" to be a limited label because it implies that gender is a binary (i.e., can be divided into two categories: men and women) rather than a spectrum of  gender identities. Some people therefore identify as pansexual to indicate that they are attracted to "all genders" or "polysexual" to indicate that they are attracted to "many genders." It is completely up to you what label, if any, feels right for you.
