Recently had a conversation with some friends and we discussed first impressions. Almost unanimously I was given the image of Pollyanna or Anne of Green Gables.
How do you counteract first impressions? I think it is really putting a crimp in my ability to get a date. I'm decent looking and have a trim and toned body but it seems like most guys think I'm unapproachable or not available. Also, I have problems showing my sense of humor until I'm comfortable around someone.
So, any tips on how to make the first impression more approachable and less miss innocent (without going overboard

)?
