Should I be worried…

Me (16) and my boyfriend (16) have been together a little of 10 months. All 10 months, he has told me he never watches porn, and I didn’t really care if he did or didn’t. Recently him and I were hanging out with my best friend and her boyfriend after our prom. Her and I were taking pictures on my boyfriends phone because he was half asleep across the room. We then saw that he had the internet browser “duck duck go”. I let my curiosity get the best of me because most people have that app strictly to watch porn. I was right, he had porn pulled up. It was on a website called “Motherless.com,” at first I didn’t care but then I saw what he was looking up. It’s called “Snuff,”. Snuff is a extremely violent type of porn in which it shows someone ((normally the women)) being murdered during sex.

I don’t know if I should be worried or not. We’ve yet to have sex so I don’t know what he’s actually into and I would like to ask him what this means but I don’t want him to get upset with me for finding out. What do you guys think?

Note : He also had the website goreish pulled up on a non private browser which is pictures of people with bad energy’s and videos of gross deaths. He’s a history geek especially when it comes to violent wars. He’s never been violent with me and he’s actually a super sweet and caring guy.
