Co-worker won't acknowledge me?

So, there's this guy, he's a bit older than me, maybe 30yo. We've been working together in a drugstore for about three months. He's always treated me in a strictly "correct" manner, he's polite and all, but no more than that. And that was fine for the first few weeks, but now it's just starting to piss me off. Just for the record, guys LOVE me - I'm attractive and I get treated accordingly. There's no reason for him to be like this, so I'm chalking this up to some dumb male pride or whatever. Still, I want him to acknowledge me as a woman because I don't like being treated as a guy - maybe for some girls it's okay but not me. I'm NOT interested in him, I just don't like his attitude towards me, especially since I see him flirting with female customers sometimes (he makes little jokes or whatever). So how do I change this? Thanks
