I am 24 years old. Through my high school life I had more than my fair share of sex partners. It seems like in the beginning of a relationship that it brings you closer together, but that's not at all the case. The guy just wants you to think that. As the old adage goes, "Girls use sex to get love, boys use love to get sex." Please don't mistake the two. Sometimes at your age things like that seem to run together and it's hard to distinguish love from the other. Love doesn't make you feel uncomfortable, and it doesn't hurt or pressure you to do anything you don't want to. Love should always encourage you to be yourself and it should be supportive. At this point in your life, I don't think you should be really ready to love any boy, but someday you will. Trust me on this one, your parents will ALWAYS be there for you. Now I am seeing what they were talking about when they said, "Someday you will understand."
Did your mom or dad ever tell you the saying, "Why buy the cow when you can get the milk for free?" So true.
As a last thought, if you have ANY feeling of self-worth, all having sex will do to you this early in life is to make you feel shameful about yourself. Sex is something you just can't take back. It took a lot of time to get over feeling like an object, like an old tissue, just used and thrown out. I am just now learning how to be me again and appreciate who I am. NEVER lose your dignity.
