I don't know if she sees me as her bestfriend but for me, she is my bestfriend.

most of my friends are female and yes strictly no sex just playing and having fun and looking out for each other giving advice that sort of stuff
sex good but i reckon frienship much harder to find good friends that is...i am best mates with my ex after ten years so it can be done

Yea he's vietnamese ^_^

my friends are girls because most guys don't like me and its hard for me to be friends with them i don't know if i'm their best friend but to me their my best friends.

I've known my bff for 15 years now. hes a very dear friend of mine...i tell him that if was ever crazy enough to get married, he would be my maid of honor XD

Strange but i think for some reason we prefer someone who is more interesting, which happens to be in the other sex as they dont know what happens to the other.

A woman isnt going to understand a males processes so maybe its seen as like a interesting thing? Guys tend to hunt for women and therefore spend more time meeting and talking to women to understand eachother.
Its like a sub romantic connection, like a special friend connection which is always what keeps a friendship strong

There is much truth in what you say. Sometimes things get a bit intimate between myself and my friend but something normally puts an end to it. One time she lifted my arm and put it around her shoulders. What's odd is that at the time she had a boyfriend so it was a bit awkward yet pleasant.

Erm.. I don't really have a best friend as such.. More of an inner and outer social circles..

If they're in the inner one I'd consider them a best friend but in the outer they're just friends? The inner circle is quite large though - Mix gender also.

I don't have "one best friend" but those who are close to me are both male and female ^_^
