The full title of the book is:

The Power of the Pussy - How To Get What You Want From Men: Love, Respect, Commitment and More!

Essentially her premise is that a single woman should date multiple men, effectively making them competitors for your time and attention. You should always have men in reserve ready to take the place of your chosen guy, should things not work out.

Don't give him any sex until he's clear about what it is you want. There is a phenomenon called 'Pre-ejaculation ass kissing' (PEAK), where a highly aroused and sexually frustrated man will do anything for sex. After being teased and frustrated for a few months, you set out your demands when he's in PEAK mode. The 'players' will have left, thus weeding out guys only after sex.

Finally, to discern whether his motives are pure, you subject him to the Prince Charming test - see if he will drop everything to come to your aid. If not, kick him to the curb and try again with one of your other guys.
