I wear contacts some days and my glasses on others.  Depends on my mood, what I'm wearing, how late I am 
 
Some guys look really hot in glasses, some it's kinda neutral.  I had a crush on a friend for a long time (from afar because I'm a big chicken).  Saw a picture of him wearing his glasses one day. *drool* Didn't think he could've looked hotter before that, but I was wrong.
