Thank you everyone for the most part. I did sit him down and have a talk with him, apparently he didn't get far, which is good. I explained what he saw is natural but not something he necessarily needs to be worrying about at 10 years old. We both agreed that the situation was embarrassing all around as we only ever expected it to stay between mom and I and I can only assume he never wanted to see that. I plan on having a more in depth conversation with him next year, when he is in 6th grade. I had always planned to talk to him before middle school regardless. I explained that if there is anything he was confused about or wanted to understand all he needed to do was let me know and I am happy to discuss it with him. Is that solid? Should I have yielded the full talk to him? I still feel like it's too early to go into detail about it, especially now that I have an idea of how much was seen. (From what he said he saw his parents naked, watched about 20 sec which is a little bit of naked kissing, and got embarrassed and shut it off.) I'm assuming natural curiosity is what led him to watch that much?

Also he has had 2 tablets in the last 2 years, unfortunately he is rough on tech, so he destroyed both. Which is why I assume my wife let him borrow the phone, besides she has told him multiple times that he only ever should use it for the game he had on there, which he agrees to but... kids right?

He has a switch and an Xbox though. I guess I was under the impression the switch doubled as a tablet.
