Seven guys is a lot for one year. You seem to have sex separated from intimacy and that can be an issue. If you keep on this path an STD or pregnancy will mostly likely occur before you graduate high school. You’re getting some need met through sex. Ask your parents if you can see a counselor. If you keep this behavior a secret life, it’s likely to get worse. Talk to an adult that you can trust as soon as you can. Others will use you and you are worth more than your sex so see someone who can help you figure out what is intoxicating you in the sex that you’re trying to fulfill yourself.
