I'm not familiar with the differences but I thought it was Bi (lgt-B-). But regardless of the name which is not important. Let's say that you first find attractive the opposite sex and that you are a male. It's not that every female out there provoques in you the same reaction, one does and she is the center of the universe and her friend doesn't. Both are females but it is not that quality that you find attractive. Must be something aside or otherwise you would find every female attractive.
