"In my interview with Rener Gracie, whose grandfather established the Gracie Jiu-Jitsu method 90 years ago, he told me there are four phases to nearly all sexual attacks on women..."

"... 1) Identify an unsuspecting target, 2) Subdue the target, 3) Exhaust the target, and 4) Execute the sexual assault. We want to fight with all our might and the moves we have above in the second phase. In the third phase, however, right before an assailant executes his sexual attack, all he wants to do is exhaust the victim and gain complete control, so fighting back actually may backfire at that point, wasting energy. Gracie’s Women Empowered training program teaches women to recognize when they’ve entered that phase where they are truly trapped and are no longer in the defensive movements phase—and to feign giving in. Pretend to be compliant (kind of like playing dead for a bear). In those split moments, the predator will think you have given up and will loosen his grip, giving you a chance get away."
