One of the keys to meeting women in a fun and relaxed way is by being comfortable around them. This means that you are so accustomed to speaking with women, touching women, making them laugh, giving them a good time, and so on that you don’t worry about being able to do these things. Note I used the word “accustomed”. You may still get nervous. You may still get excited. Those things are fine, and indeed are good. They will add tension and spice to the reaction. If you can feel comfortable with a woman and build sexual tension, she will reflect that.
