If you really want to be able to make a powerful and lasting impression on a woman, then you have to be able to sexually attract her. Without the right amount of sexual tension with a woman, you are going to be spinning in circles trying to get anywhere with her.
The struggle that many men have with women has continued for a LONG time and probably will continue on for a much longer time as well. You can change that for yourself by simply learning how to build and create sexual tension with women. Most guys shy away from doing this.
Most guys have a TERRIBLE time when it comes to getting a girlfriend. Well, I should rephrase that a bit. Most men have a hard time getting a girlfriend that they REALLY want. Instead, they will end up just floating around until they find a woman that seems to be better than nothing.
