Not sure of orientation and fall for my friends (i'm a guy)....?

While there may be some truth to you being biual, you say that you find yourself attracted to guys who are not like you. Ask yourself (honestly): Could it be that you are wanting to be like them? Are they are everything you want to be? It could be a simple case of envy but not of a bad nature. Many times people are attracted to those who portray a certain image and usually it is how they would like to see themselves portrayed. Good luck.
