Am I right to be bisexual?

Of course, you certainly aren't wrong.

Remember: it is nothing wrong to be who you are. It is right to be whoever you are: not often bisexuals, lesbian and gay but also straight, asexual, etc. If you are born as bisexual, do not get concerned about it, cause you are not alone in the world. And you can join in some bisexual support groups such as BiCupid, then you will find that there are more bisexuals than you can imagine in your nearby.

May your parents and your close friends are not understanding you, so you feel sad and dispirited, in this case you can try to account it for them. But if others around you don’t think you're right, tell them to screw themselves and keep their opinions to themselves, let them go against it for their religion or homophobia and you leave alone it. Because their opinion doesn't matter.

How to do who you are and what is right to your sexual orientation depend on yourself rather than others, bisexual is not a crime.

Finally, if you like both genders, it's nothing wrong being bisexual. But if you are not into both genders, it is not a right thing to be bisexual.
