all u need to do mate is this

stop looking at meetings with girls as... Will she sleep with me!!!

and think this...

Ok is she worth sleepin with ?? its not her choice its yours! its not an interaction to try & get laid, its to see if she is worth sleeping with.. or seeing again.

If your in control in your mind.. then ur in control. And dont be scared to say, "im not just gonna jump into bed with sumone i dont think is worth it...." if they get their back up FUCK THEM, move on
