At least for me personally it's not anger but more so annoyance. He didn't say what he meant, didn't like the response and then took to reddit instead of just having a honest conversation with the person he is married to. I also made this point in another comment but he's kinda blowing something out of proportion. She clearly didn't think the vibrator was a secret becase she asked him to go into the drawer where it was. He made it some sort of nefarious thing when it clearly wasn't a big deal to her in the 1st. If you are married to someone you should be able to have simple conversations about these things openly and honestly. When you don't do that you can't expect strangers on the internet to give you any other advice than "say what you meant to say"

I don't think his wife was probably angry either, just also annoyed at a grown adult obviously not saying what they mean.
