That IS a funny question, isn't it? It's like someone asking how you know if you love someone. You just feel it and know! I am bisexual too. I've not been comfortable being very open about it until lately, so I've not suffered this silly question like you have. But I've always felt attraction to both sexes. I never fought it or thought it was wrong. I thought it was unusual and that many others would think it wrong and therefore it was something I should hide when I was young, but now bisexuality seems so natural to me that I wonder how someone could only BE attracted to one sex or the other! Not that I think heterosexuality or homosexuality is wrong, but I can just hardly relate to the limitation in finding beauty and attraction. Thanks for posting this and being so open.
