Every woman has hardwired into her head a behavioral circuit that works to protect her from getting pregnant by a man who has no intention of sticking around to help raise the child. The resistant behavior this emotive circuit elicits right before first-time sex is called last-minute resistance. It is your job to ease her through this uncomfortable emotion should it arise. Having sex carries a much larger risk and investment for a woman than it does for a man from an evolutionary perspective. Last-minute resistance is her last line of defense before the point of no return.
