Am I a sketchy guy??????????????

Staring at a girl is not a good way in showing her that you are attracted to her. Lots of guys get labeled as creeps because of that. If you find her attractive, best way to sure her is to approach her with a kind and sweet soft smile on your face. Not a creepy grin with teeth all showing. That would make you look creepier. A smile with your mouth closed looks polite and harmless. Well after the approaching, strike up a nice conversation with her about anything like the weather. I know a guy who is like you. Except he thinks he has been misunderstood by a lot of women when the truth is he doesn't know how to behave around them. Don't worry. He was a lot worse and you don't sound that bad by the things that you do.
