Here's a couple of guidelines when approaching me.  A) Dont assume because I'm so forward with my profile that it means its you who I want, chemistry is key.  B)  If I politely say I am not interested, I wish you would politely go away instead of turning into a blubbering desperate shell of a man.  C)  I have a brain and I use it.  If that isnt okay with you, then you can move on.. I wont mind.

On the flip side.  If you approach me and are able to understand that a girl like me has two sides to her.  You have to get through the front door before I let you in the back.  Mutual respect is what I desire.  If we hit it off and choose to take it further, THEN you can treat me like I say I want.

Dont assume anything.  :)
