I was hanging out with an older man for a good while until I realized how wrong it was
You're kidding, right? Was he trying to take advantage of you?
Yeah, I feel so stupid for putting myself in that situation.
It's a good thing you realized what he was doing and that it was wrong. That would have been a really unhealthy relationship to be in and it's great that you ended it. He might have tried to make you do some really sketchy stuff.
He asked me to send him pictures of me naked but I said no.
Wow, that's really shocking and I am really proud that you didn't give in! That sounds like a really unhealthy dynamic you had, and I believe it's best to try to report him to the police, especially if you are underage. You can't let things like this get away.
