Anyone trying to draw a universally right and applicable conclusion on m/f relationship is just being plain stupid. I'm not saying all the answerers above were completely pulling out loads of horse***t here. As a Chinese you might hate what the Party tries to teach you about Marxism/Communism over years, but you do, however, lack the basic perception of philosophical methodology. Question is what are you gonna do if I told you yes go ahead there sure is, and what are you gonna do if I told you no forget about it, how come you believe such nonsense? Does the "turth" of the topic have any actual effect on you, honestly? Let's say you know this girl, Mary. After couple of attempts you finally learn that you cannot become platonic friends with her, then you give up. Does that mean you wouldn't become friends ten years later from now, or ten years earlier back? Let's say you are friends now, does that mean you'll be in the same sort of relationship 24 hours later? You ask a particular girl, "can we be like, pure"? She says, "yes sure, we can and we now exactly are". Does that mean another girl, or any other girl, will say the same, or will all say "no"? Does that assure the same to another guy and another girl's case?

Of course, but it's hard to come by.

Yeah. I can name some guy friends I have completely platonic relationships with.

Yes, of course there is, but it's rare, especially for a long time

I think that there is no pure relationship between man and woman.we are not angels neither prophets.at least they kiss each other
