How do I get over my weird attraction to a friend?

So I have this friend and we're pretty easygoing together, but I've lately noticed that I've become physically attracted to him. Hugging and other types of physical contact have caused an awkward hormonal rise in me and I'm suddenly jealous of other girls who he pays more attention to. Emotionally and intellectually, we're just good friends and completely opposite from each other/incompatible dating wise, but this physical attraction I'm having is making things confusing for me.
