I have fallen for 2 guys and they want an answer and i cant decide through fear of loosing them both...?

Well clearly, you prefer Guy 1. You talked about him more and the things you said were better than about guy 2, and I'm sure you've already figured it out by now. But yes, you do need to be honest about this whole thing and only go out with one of them. I know that you don't want to hurt either of them, but if you choose guy 1, it's better that guy 2 knows now rather than you leading him on.
