I don't know, but I do know that all girls like girls. All girls are either gay or bi, it's just the way we are. Most girls are taught that it's wrong- whether they realize it or not, and even if they think they believe that it's okay, they would never try it for themselves- by society and through other ways, and just assume they are straight and never act on the little wantings that make them feel maybe they aren't. There was an article about this a long time ago, but I could not find this article just now when I looked. If I find it later, I will try to edit this and include the article.
I don't know if all guys are also a little bi, but it could be. Like, my father told me that he's like 99% attracted to girls, but 1% attracted to guys (weird how close his wording was to yours, right? Maybe you're really onto something here!), so it's totally see-able. I don't know if all guys are that way, though, even if they were willing to admit it and/ or try it. But that's a very well thought out question, and I'm glad you asked, it really made me think!
