I, (20F), have only had sex once. It was with my first ever boyfriend, and three days after we did it for the first time, he broke up with me and cheated on me. This was about 4 years ago, (almost 5 years ago). So far, I’ve had another boyfriend, but we ended up breaking up, (mutual), but we’re still friends. I am nervous to have sex. I am scared that if I have sex, they’ll break up with me like last time. I want to stop being afraid, but I don’t know how.
