How can I attract females without looking like a creep or asshole?

I like men with a sense of humor who is witty, and confident.  Confident can get a gal.  Also, a guy who is a gentleman will be able to woo a girl.  Open the door for her always, drop her off at the front door when its raining, etc.. Also, being well dressed and not stinky is a good plus.

Depends on what you mean by "small details".  They could either be interested or disgusted.

His talking about mail order brides for insecure guys.

You mean Adams apple, bad breath, yellow teeth, sweaty face, noise hair.

The reason for dating is to get to know the real you. 

When you say that girls don't want to date you tells us that their is something odd about you.
