Super Paranoid!

So like two years ago, I sent like one photo to a guy of my boobs, and I'm getting so paranoid that he's kept them. I've asked him a few times and he said he hasn't got them, which is believable because he's a Christian and would get told off by anyone if he was found to have it, but I'm still so paranoid that they might get out! Any ideas to help ease my paranoia?
