Is My mom overreacting?

My mom saw a smut someone wrote in my computer history. I'm 16, so isn't it normal to be interested in ? I wasn't watching or looking at naked pictures IT WAS WORDS. So she was telling me how disappointed she was because it's LIKE and instead of talking to me about it first, she told my older sister, and now I can't have the computer. She tried to make me feel ashamed but I'm not. I know other teenagers are out there looking at naked people and having (not judging you if you do that, just saying I don't) I've never even had a boyfriend, what is she freaking out about? My little sister is racist and tells me to kill myself, my older sister's boyfriend was arrested for steroids and other things I won't say, and she's disappointed in ME??? She acted like she just couldn't believe it. Am I supposed to feel bad because of my interest? Especially since I don't even want to do it? Yeah, I like reading about it, but the idea of doing that freaks me out, to be honest. I also read that by scolding your kids for things like that, you may make them ashamed of their uality. I used to feel really bad that I would sometimes think perverted things, so I googled it and a ton of people do, that's how I found out that shaming your kids is harmful. I mean, would she rather I be out doing it myself? What harm comes from reading?
