I don't think a friendzone exists. I don't think that, just because someone considers you a friend and doesn't want to be a relationship with you right now, means that they never would. Just as people 'fall out' of love, people can 'fall in' love at any time. Just because someone considers you a friend today, doesn't mean you'll be 'just' a friend tomorrow.
Everyone should just respect the fact that people are either attracted to someone or not attracted to someone, in a sexual way. It's not something that can be controlled.
And there is no one sort of 'guy' who would end up being friends with every girl they meet. That's ridiculous. This concept is so stupidly sexist too, because I have never seen a girl complain about being 'friendzoned'.
Just be glad to have that person as a friend and look for intimacy elsewhere. Don't bitch and moan because someone doesn't want to go out with you - attraction is never a choice. You are never entitled to sex.
