Hi, M.. You sound like a very smart and caring young woman! It is clear that you want to do the right thing, and you certainly don't want to hurt your Mom. Becoming sexually active is a big decision and one that you should carefully consider. Three years is a long time to date someone and it is understandable that you and your boyfriend feel a very strong desire to express your affection. Because it sounds like you are mature and responsible, you will understand that becoming sexually active is about more than just having sex. You need to consider whether or not you are ready for the emotional and physical side of this choice. Your mother is concerned for your overall person and she wants the very best for you. Since I don't know you or your mother, it's hard to advise exactly how to resolve this dilemma. But if you decide to become sexually active, you must protect yourself not only with some type of birth control, but also your boyfriend should always use a condom. ALWAYS. Dear heart, this is an exciting time for you and life is full of beauty and wonder. Perhaps you might take a step back and consider that there is a lot of time for you to grow, mature and learn more about yourself. Your mother has your very best interest at heart, and maybe the fact that you may have to lie to her, or act without telling her, indicates that becoming sexually active is really not in your best interest right now. Even though your Mom might freak out, talk to her. Try to understand why she feels the way she does and ask her what concerns her the most. And then listen to her loving advice and concern. You can write out what you want to say to her and remember that she may be upset, but she also will want to be sure that you have the very best life you can have. That means not getting pregnant before you are able to be a good parent, and not getting a sexually transmitted disease, or perhaps, not getting hurt by having a sexual relationship that breaks through emotional boundaries. You might begin by saying "Mom, I love you and don't want to upset you. I want us to be able to talk about things that are important to me and I'm thinking about becoming sexually active. I want to be sure that I am protected and I don't want to keep secrets from you because I love you and I care about our relationship." She may freak out, but that's OK. You've been open and honest and if you are going to become sexually active, you also need to be honorable and forthright with your family. I'll be thinking of you, and I hope that you are able to make the best choice for you. God bless.
