A lot of males all around the world want to know how they can become more confident and relaxed around the opposite sex. This question actually has to be broken down into several steps and the roots of the solution go a lot deeper than you can imagine. The first thing you have to start working on is your beliefs and how confident you are in everyday life. If you are not confident around women and feel that you can't relax, there is a pretty big chance that you lack self belief in other situations in life also.
Therefore you should start identifying the arenas you feel uneasy in and start working on them by putting yourself in those situations as much as possible. Slowly but surely, you will start to get desensitized towards these situations and you will start to become a lot more relaxed.
The next step is to start working on your personality and actually figure out who you are as a person and what you stand for. This includes finding out what you look for in the opposite sex and what kind of behavior you will like and what kind of behavior you feel pushes your personal boundaries and what you are willing to accept.
Too many males constantly whine that they never meet a sweet girl but when I ask them what they look for in a girl they don't even know what their dream girl would look like or behave. It is very important to write all of these things down as you can never find something if you don't know what you are looking for.
The next thing is to stop putting females on a pedestal. They are humans just like you are and the majority of women might like it in the beginning when you put them on a pedestal, but in the long run it bores them and they lose all respect for you. Once you get these steps covered it is time to start improving your communication skills. You do this by approaching people everywhere and it doesn't matter whether they are males, females or old people. After a couple of weeks you will become more confident with your communication skills and you will automatically become more relaxed around females. This will lead to you getting more dates and gaining even more confidence.
