Your statements towards women must be unconditional, otherwise it’s not really being vulnerable. If you tell a woman that she’s beautiful only because you think it’ll give you a better chance of sleeping with her, then amazingly, she will not be very flattered. Try it. It’s true. Give women false compliments and see how they respond. They won’t respond very well. But communicate with honest appreciation and you’ll be amazed how she lights up in front of you.
