no, you should feel deep down if you are or not, i know i do. its kind of weird being attracted to both guys and girls just remember don't let anybody tell you who you are thats for you to say not them. if you decide to get with a guy relax and enjoy.
yeah exactly, you should sort of know by now. but if you just feel experimental and curious then that's cool but it doesn't necessarily make you a "bisexual": there is a difference between who you ARE and who you WANT to be.
I can't imagine what it would be like to be attracted to only one sex or the other. Being bi for me feels natural. Whatever you feel is what you are. Whatever feels natural.
