Always SMILE! It is a turn on for guys. When I first met my boyfriend he was working at a mall outlet and I was walking by and I looked at him and smiled, then he looked at me. We couldn't take our eyes off each other (seriously, I'm telling the truth). About a week or two later I walked into the store he worked in with my sister. Her friend went to go pretend like he was trying on shoes, so that I could make time to get him to talk to me. I looked up at him and he walked over to me, asked me if I needed anything, I said "Actually, I need the time please" he said "1:40" I smiled and said "Thank you...um" then he told me his name and he asked me for mine. From there it was history.
I was so very nervous at first but all I could do was smile around him. Not even realizing it was pulling him in.
SMILE girly, it always works!
