I keep getting told sex is great but im scared. What if my boyfriend isn't the right person? Im scared it will hurt!. My friends say its great but i know its gonna be awkward and im not gonna like it. My boyfriend keeps wanting to do things but i just cant do it yet. What is wrong with me! Its like i want to do it but i dont....if that makes any sense. Can someone help me or am i a lost cause?
