there are two types of male friends for me - 1) buddies, 2) close friends. the difference is that I don't really see buddies as men, they actually have no gender for me. also - these are guys that I just hang out with, usually in groups. so we are not close, but we are still friends.
close friends are different. I do believe women and men can be friends. real friends. I also truly believe if a man and a woman have an emotionally close friendship there actually is something in the air... sexual tension... because, really, besides them having a very friendly and nice personality, they have also been attractive to me. I know they have liked me as well.
then again - I can admit someone is attractive to me, yet never feel the urge to try it out. that there are always reasons not to do it.
for example - my best male friend at this moment is... I don't know what his type is but I know his stories with women etc, I know I might hurt him. he is a gentle soul and I might be too harsh sometimes. no, he is not a crybaby or an emo or something . I also have a feeling we might get too attached to each other.
all in all - our friendship is better this way. I don't see much potential for a good relationship, I'm quite sure it would be shitty.
not to mention that I have a boyfriend that I'm madly in love with :P
