Both of you have to understand each other first. Let me give you some educated advice young lady, you are too prohibitive and afraid expressing yourself to opposite sex showing the guy who you are. Listen to this approach him ask him to go for a cup of coffee just to know and get acquainted to him. You will never know whether he is the right person for you until you be with him for a while or longer. One thing you should not do is going to bed with him until you make certain that he is the guy.
