I have been interested to know if bisexuality really exist. I have been told by a phychologist that a person can only be gay or straight. I thought a lot about this. He was very adamant about it. But I always seemed to doubt the correctness of this. He always used to say I was having an identity crises and that's why I have felt sexually attracted to men and women in my life. I live in South Africa. I don't know if psychologists here believe different than other places, but please give your opinion? I'm confused. I need to know.
