Bisexual error -

Being bisexual isn't bad. You like who you like and if that means liking both men and women, then that's perfectly fine. It's your decision whether you want to tell people or not. If you want to tell them, just sit down with them, preferably in a public place where they can't make a scene. Just tell them with a calm voice that you are bisexual. As for defining bisexuality, it simply means that you're attracted to both men and women. You don't choose who you fall for. If you would fall for men and women, then that's how it is. Don't let anyone tell you that it's bad, because it's not.

Your sexual preference is what it is. Whether it is 'good' or 'bad' is a concept that has been put into your head by religion, which stigmatises sexuality as a means of social control. You are only 15. I would suggest that you are too young to be certain what your sexual preference is. Studies on human sexuality have found that varying degrees of bisexuality occur in roughly half the female population, especially when they are young. Do not stress about it, but do not tell the world either. There is no shortage of people who will want to vilify you because they think that you are different to them. Keep your own counsel and wait until you are older to decide what you like, or not.
