Men... they like a challenge. Women? Woe is I for I have plenty!

If one is attracted to another then the answer is NO (exceptions dont count).
A lot of women seems quite Nieves about it.

I've always had way more female friends than male, so I'd have to say yes. But then, I'm the sort of sensitive yet straight male that women like to hang out with. I can't say I never had sex with any of them, but we almost always went back to being friends afterward, for I'm "fun to be around but not relationship material". There were also plenty that I didn't. So yes, it's possible, but there's no guarantee that that's all it will be in the end.

And by the same token, I've been friends with quite a few gay guys with no sexual tension on their end, so that's possible too. Maybe I'm just not sexy for that side of the fence.

this will lead to another question:
can a man and another man be Just friend?
sorry but i just had to spit it out.
and of course man and woman can JUST be friend. as well as woman and woman.

The majority of people I consider to be good/best friends, all my life, have been male. Gay, straight, transvestite, whatever. The answer is yes. But if you can't control your genitals around the opposite sex, that's your own problem.

I don't think so.. there's always some kind of attraction between

Yes but alone maybe not lol just sayin......Oh but don't get me wrong it depends on the situation.

Of course they can.
More or less it's figuring out whether the other person is attracted you.
If they are...then there's a risk that being "just friends" probably won't work.
But...there's always a chance that they are attracted to you but value the friendship more.
(In a way that they can handle).
And sometimes there isn't a merit to dating someone whom you're too good of a friend with anyways.
(Too awkward at times).

I assume so, this is based purely on conjecture as I have no friends to have experienced this situation with.

A relationship between any two people is always a unique situation. Each and every person has their own personality, and each time those personalities meet the interaction will be different. Factor in the reality that all relationships evolve over time and it makes any broad statement like, "men and women can't be just friends", ridiculous. This is stereotyping, and its not a very healthy way of thinking.

BTW, with regards to the original poster and his situation. I can only try to make inferences based on what you've told us, but it sounds to me like you were being used as emotional support while this girl's BF was gone. Especially since she stopped calling the moment he was back in town. Are you wrong that she was starting to have some connection with you? Probably not, but she also likely had no intention of carrying it further. Don't be surprised if she resumes calling if he leaves again. If that happens, you have to decide what you want to do. Are you okay being in a relationship with someone who (whether she was consciously doing it or not) was turning you into the equivalent of an emotional bookmark to suit her needs, and just as easily put you aside when her "real" relationship resumed. I know that sounds harsh, but there was one other thing that I really picked up on from your post. Your hurt. This girl and what happened have really hurt hou, and you're lashing out here where the internet makes you somewhat anonymous. I wish you the best of luck, and try to be more open in your thinking and your view of the people around you. You might find there's a wonderful woman who's already near you that honestly does want to be more than just your friend.

I think one problem with men and women being friends is that people tend to want to have friends of the opposite sex that they are physically attracted to. If you make friends with someone based on who they are as a person, it would be a whole lot easier to befriend the opposite sex.

You can be just friends, that is completely fine and is wholly acceptable. Yes, at points it is almost guaranteed that feelings from one of the given individuals will rise yet whether these feelings are lustful or contain a deeper meaning meaning of love is questionable. Given the latter option and considering that the given other holds feelings of similar value, then there are chances that the current friendship is capable of expanding into something larger. Lustful feelings, on the other hand, will come and go, it is wise not to let these feelings become the source reason for ruined friendship between male and female. I personally, have many a female friend, i have also become attracted to 2 of them, but my feelings passed as i realised that i only viewed them as friends, nothing more, nothing less. We continue to be just friends to this day. So yes, it is possible to be friends with the other gender, sometimes though, being friends with the other gender will require an alteration of mindset.

Honestly, they can't.
I mean, they can be, but, that man will always have some sort of an attraction to his lady friend. No matter what. She might as well. Unless he or she is homosexual. The maybe it's possible.

I think you can be friends if you love someone else more like i ended up falling in love with this girl and she was my best friend but because of that i can be just friends with other girls no matter wat happens just friends.

They can.
Even teleportation is possible in principle
