<human>: Can you succinctly summarize the text in 1-3 sentences?

I am a girl living at home while going to community college. I probably will not be moving out soon. My mom is a housewife and my dad works from home, so we are together a lot of the time. I already knew my dad likes porn, which I don't have a problem with. My mom doesn't like porn, and has told me I shouldn't watch it. As far as I know, my parents haven't really discussed their views with each other, but I don't know. My problem is that I glanced at my dad's download list on his laptop when I went into his office to ask him something, and it was full of porn. I was surprised it was so much, but I didn't say anything. I have seen his download list several times since, and it as been new (and disgusting, judging from the titles) porn. Then last week when we were sitting watching tv, I glanced at the ipad in my dad's hands. He was just browsing through vintage pictures of topless women. This happened again tonight. I was shocked, because I knew if he knew I could see his screen he wouldn't do it. I'm worried he's becoming desensitized to naked women. I don't want that to effect his relationship with my mom.
I know he thinks my mom is beautiful, even after being together 25 tears. I feel like this may be partially my fault because I don't think I'm out of the house long enough at a time for them to do anything.  My mom has said I don't need to worry about them, that they are happy and doing just fine. I don't want to alienate my dad by shaming him. I don't want to fuck up my parents' relationship. He is a great dad, and loves his family dearly.
<bot>: My dad has gotten sloppy about hiding his massive porn viewing, and I'm worried about the effect his possible addiction may have on his relationships with his family. I'm having a panic attack.
