Just friends?

Men never want to get to know women for strictly platonic reasons; it isn’t within their nature. If anyone claims they want to form a friendly relationship, they’re lying. Unless it’s in response to you turning them down in which case…um…nope they’re lying about that too.

Don’t fool yourself, your friend has absolutely no interest in anything you say. It is a well-established fact that men and women cannot be friends. At one point the sexual tension becomes too much to bear.
Hey, we’re red-blooded individuals here, we all have a libido to give in to.

It’s like in When Harry Met Sally, Harry says: "Men and women can't be friends- because the sex part always gets in the way."

You don’t actually have to be having sex for the sex part to get in the way it’s just the fact that one of you wants it. It’s the thoughts that get to you.

Even when you are both involved with other people, you can’t be friends. This is mainly because the person you’re with cannot fathom why you need to be friends with the person you’re friends with. They'll always think you’re hiding something.

If someone of the opposite sex is talking to you, they want to get with you. You can't just be friends.

Unless one of you is gay…then you can be friends.

Harry: No a man can be friends with a woman that he finds attractive. He always wants to have sex with her.
Sally: So, you're saying that a man can be friends with a woman he finds unattractive?
Harry: No. You pretty much want to nail 'em too.
Sally: What if THEY don't want to have sex with YOU?
Harry: Doesn't matter because the sex thing is already out there so the friendship is ultimately doomed and that is the end of the story.

Cheers Harry!
