no string attached r/s is the problem.
one of my female friends who is quite open-minded, told me before
her crush proposed to her to be his f buddies. i told her to go
ahead since she always like him.
but she said the problem was she had feeling for him, and she might
afraid that she will go crazy so she rejected him. to this, i felt
the same way too. 
i think ons or regular f-buddies might not seem smooth as one might
think they are. hope pple who have desires better think twice in
handling well. r/s is not a game!
