Another missed opportunity

Unfortunately my wife and I were always just a little too shy or conservative. As for me, I know what a pervert I've always been and I suspect my wife is/was too. Sometimes the sex was hot but I feel it could have always gone to another level. Sadly, I think we were both afraid to show each other our "darker" sides. I feel like now that I am sex deprived and horny all the time plus having access to as much porn as anyone would like, thanks to the internet fueling my perversions, that if we had ANY sort of sex life, I would be so direct and tell her what I want and what I want her to do.
About 15 years ago when our son was very young we were on vacation staying at a relatively cheap hotel. It had a pool and a sauna.
We had spent most of the morning and early afternoon having fun with our son and now it was time for his nap.
Being the closeted pervert that I was, I told my wife I was gonna go check out the sauna. Of course, I was already hoping for some kind of encounter. She said ok, that she would stay with our son and nap too.
Sadly, nothing happened in the sauna. Not a soul to be found. I lingered as long as I could...occasionally stroking my cock in my swim trunks...just in case someone came in... I'd be ready to present something to get someone's interest.
When I made my way back to the room my wife appeared to be sleeping but for all I know she may have been lying there playing with her pussy the whole time...because she was very interested in hearing about my visit to the sauna. She had this subtle curiosity/sexy interest. I can't remember what she had asked...but I picked up on it pretty quickly. This quickly escalated into quiet dirty talk...I went with it and told her how a woman had come in and sat across from me in her bathing suit..and how we made small talk and then the woman asked if I minded she took her top off...my wife moaned a little and I knew I had her. My hand was in my wife's shorts and playing with her 35 year old landing strip asian pussy. I could feel her getting wetter...so I knew she was enjoying it. I told her how I started to get hard and how I pulled my trunks to the side a bit so the woman could see my cock peeking out. I told her how she saw it and thought it was nice.
I remember my wife asking what happened next ? She asked me if I took it out ...when I answered yes...she moaned a little more.
I told her how the woman...that I didn't know, knelt down in front of me and proceeded to take me in her mouth.
She really liked that...and then she asked me something that she had never asked me before...
Did you cum in her mouth ?
My wife and I had talked dirty a little..but usually about scenarios...not ever using words like cum or cock or pussy
When she said that..I almost came all over her hand

By this time we were both so turned on
We quietly but very passionately fucked while our son slept.
It was so hot...for our fairly vanilla, repressed sex life.

A couple of years later we were on another vacation in the winter and the resort had an indoor pool and yes, a sauna. After spending some time in the pool with my son I made my way back to our chairs. I sat there with my wife and then said
I'm gonna go checkout the sauna
Again, no-one there
When I came back to the chair pretty quickly, my wife slyly asked me
What's the matter? No-one in the sauna ?
ANd I just smirked at her.

I say this was a missed opportunity because I could have and should have used this to propel our sex life forward. I could have gradually unpeeled the Hotwife that I think my wife could have become.
