(NSFW)How does one keep one's homones in check when people we "want" are around?

I have a friend whom I find incredibly attractive. Not just physically, but intellectually. He has so much in common with me, and I feel as though he has experienced and researched things I’m very interested in learning about. I feel I could learn a great deal about life from him. He seems to have a deep inner wisdom which I am very attracted to. However, we are going opposite directions in life right now( He’s spreading his roots in this county, and I’m pulling mine up). We also have very different communication style. I tell things like they are, and like straightforward communication, and he’s got this whole mysterious hints thing going on that drives me a little bit crazy. We’ve talked about it and agreed that it is not for the best. Anyway… when ever I am around him my hormones go all insane. I get ridiculously horny, and I start getting all stupid and smitten. I really want to pursue a strong platonic friendship with this person. How can I make the hormonal/in love bullshit go away so that I can just be friends with this person? Is there a way to “turn it off”?
