Hmm I think it's possible but somehow it's just kind of difficult to maintain that friendship. Like what DiT said earlier... we might think about friendship with them only, but for the other party, they might think differently from us. For some point, from close friends, 1 party or the other might develop some extra feeling towards the other. But, I have a few close guy friends. However, I have a few close guy friends before which ended... they have some special feelings. :S
