Would it help to think that (mostly) people aren't bad... we just do bad things sometimes? I think you sound like a pretty good person. It's normal to be interested in sex, and I think it's normal for kids to act out sometimes. There may be a few things you've done that you realize weren't good for you (or others), but that doesn't necessarily make you a bad person. Just try not to make the same mistakes in the future. Recognize that you're still learning & growing, and mistakes are part of that process.
