So women's risk lies in sex before commitment.

As a man, my risk lies in approaching women.

How can I reduce this risk?  It is a common theme on this website that NAWALT.  So what traits can I screen for, before I approach, to determine if she is  "not like that".  Is this even possible?

Input from "beta" women appreciated.

In other words, from across the room, how do I know to approach you, the good girl, rather than the b1tch next you.  Help me, help you!
