Once you hear explicit details you can not unhear them. I had the experience of discovering my WH's A when he passed out with a skype chat open on his laptop which was sitting on his chest. There were statements made that I can never unknow, yet they screamed for explanation once I knew them. They are why I have difficulty feeling any love for my WH.
I would suggest that you take those unasked questions you have and write them out for your wife. Ask her to answer them now, put them in an envelope and hold on to them in case you change your mind later.
It is possible that later your brain will start filling in those details on its own and you will have mind movies. Those mind movies may be worse than the reality. At that point, reading the real explicit details would be beneficial.
The reason you need her to write the answers out now is because she will forget. ALL wayward forget.
Some forget because they don't want to remember (compartmentalizing).
Some "forget" because they don't want to tell you. (lying)
Some forget because it just wasn't a detail they payed attention to at the time and as they get further away from the event, more detailed is forgotten. (being human)
If your WW writes the answers out now, you won't be tormented by her "I can't remember" answers later. You won't have to figure out if she is comparmentalizing, lying or just plain human.
I am glad you feel content right now. You deserve a mental break. But please do not be surprised if you fall in to a pit of despair later or rage on a level you have never done before. Those reactions would be VERY VERY normal. R is referred to as a roller coaster for a reason.
