Question for guys: is friendship always platonic with girls?

Well, I'm friends with a couple girls, and yes, sometimes an urge comes over me. Now, maybe that is a part of my biology. Maybe it's because my testosterone flares, Idk. But every once in a while they do something that strongly attracts me to them. And yes, sometimes, they annoy the #@$% out of me. I don't think that it makes any difference how close she is.
