Have you tried Control G?

He's probably looking up all sorts of weird stuff he either saw online or heard at school. I wish sexual-health websites had been a thing back when I was a high school student in the early 1980s, to debunk all of the stupid myths and BS that my friends were always spouting.

If the son was acting weird I don't see the issue with a parent investigating, cause it looks like the only reason op decided to look was cause the son gave em reason to. If you give your parents a reason not to trust you or give them a real reason to be suspicious than expect them to check up on you. I mean if you do screw up your parents get blamed for not raising you right, more importantly they wanna protect you and keep you outta trouble. It's not being nosey it's being a concerned parent.

This is one of the cases where the snooping isn't out of line. The parent didn't do it for ***** and giggles, but because the child was acting oddly about the computer. That's reasonable motive to look, depending on age.

did the possibility occur to you that your son knows you're looking through his Internet history and decided to Google ****** up things to mess with you?

Depends on how old he is.

Now Im curious about these things too...

I think he's trolling you.

Either we knew you were sneaking on his privacy that he intentionally did that to troll you or he was just searching something funny to post as a meme.

Super kinky.
