I am always nice to women when I first meet them, unless I have decided I need to IGNORE them and let them WONDER who I am and DESIRE to meet me. I remain NICE until I can make the connection, then I let them know I am VERY SEXUAL... IMMEDIATELY! I NEVER let them attach a monetary value to their pussies though. That is a GRAND mistake!
If you are talking sex to a girl and she starts talking about dating or buying stuff or going places, she is NOT in the correct frame. Validate what she says and get her BEFORE giving her any of that stuff :) Her only incentive in that case is to get with you so she can get the promised items. If she gets them before you get sex from her, you're pretty much fucked up :) The better thing to do though is change her state of mind so that SHE wants sex and SHE wants you and SHE is chasing you instead of the other way around.
