How do I confront my boyfriend about finding child porn?

I live with my boyfriend of nearly five years, and we have a pretty good relationship. Not long ago I came across a picture CD that was with some items of his that had been in storage. The CD was titled "pixxx." Curiosity got the better of me and I put it in the computer. However, I was horrified to find that they are photos of very young girls, children, in their underwear and in sexual poses. They appear to have been from various sources and likely downloaded from the Internet. According to the file creation dates, they were burned to the CD about six years ago. My question to you is: Do I confront him and see what he says, or do I just bring it straight to the police? Do I turn him in or do I drop it off anonymously? I am torn because I am having a hard time accepting it is his CD. I didn't think the man I love could be that way. Maybe it could have been an old roommate's CD? This is horrible and devastating, and I need a little advice. Thank you.
