<human>: Can you condense the text into three sentences or less?

I'm not sure what it is, but lately I've been attracting a lot of attention from girls (I'm a 22 year old male in uni), and, being a shy, awkward guy, don't really sure how to let some of them know that I'm not interested without making up some lie. 

For example, tonight while I was at work a (slightly intoxicated) girl came up to me and started talking to me, just making casual conversation. At one point she said something about not usually drinking, but if she wasn't tipsy she wouldn't have been able to come up and talk to me like she did. At this point I realized it was a little more than friendly conversation, but I empathized with what she was doing because I've been in that same situation, and would have felt badly now not being friendly. She stuck around and talked to me for a while longer and then asked if I wanted to exchange numbers, and I said yes, not really knowing how to nicely say no. After the number exchange she went in and kissed me on the cheek. The thing is, I think she was going for an actual kiss and I moved my face away from it, but I'm not sure, and I feel really embarassed about it. Because of the circumstances of where I work, I would have to see this girl quite often, and don't really want to make things weird.

I don't know, this type of thing has been happening a lot lately and I feel like I'm leading girls on, but I have a pretty specific type of girl I'm interested in and, I hope I don't come off as shallow saying it, I'm not really attracted to girls outside of my type. I honestly can't help it. But I really don't like making people feel bad, so I'm not really able to tell girls I'm not interested. Now that I see all of this written out, it seems kind of pathetic, but coming from a pretty socially awkward guy, I really just don't know what I should do. How should I respond in these types of situations?
<bot>: I don't know how to let girls know I'm not interested, and really feel like I'm leading them on. Help?
