If you love her and care for her, I would advise the two of you to get married first before having sex. It is such an important thing in life, it is not to be taken lightly. We hear every day about people who have used sex irresponsibly and regret it. A person is not a car that you can take for a 'test drive'! You wouldn't want someone to do that to you, would you? . . If you are too young to get married, I would advise you to wait until you are older. Many, many people have children of their own before they have finished their education and have good jobs to be able to provide everything that their babies are going to need. Sex can't be used only as entertainment. Keep the ultimate purpose of it in mind. If you are not financially prepared to raise a family-- that means finished with college and a ood job-- babies will make your life m-i-s-e-r-a-b-l-e.. . It generally is a little painful the first time, but even if you don't wind up having babies that you are not prepared for, the emotional pain of that memory can be worse; when a person realizes they were wrong later in life and are haunted by the memory of their first lover whenever they have sex with their lifelong spouse. That is why it is best that the first one and the lifelong spouse should be one and the same person. . . Besides, nobody wants their partner to be thinking and comparing them to all the others, "This one was better, not as good as that one, etc." It takes imagination to have good sex; in fact, researchers and therapists say that imagination is the most important part of being able to have good sex. So why throw away imagination by having too much experience? . . If your girlfriend loves and cares about you, she will respect your wise decision to wait until the preparations for life are ready before having sex. When she sees how mature you are, she will have more confidence in you and love you more. . . (If she tries to change your mind for you, do you really want to have a relationship with a girl like that? I'm not saying anything against your girl; I just don't know what she is like. Don't let anybody talk you into doing something without thoroughly considering all the possible outcomes!) . . I realize this is probably not what you wanted to hear, and not what everybody else is saying. But sex is SO important, I wanted to make sure you heard both sides. Please seriously consider what I have said. . . You sound like a responsible fellow who wants to do what is right. I hope this helps. Good luck!
