Could you explain more about your reaction to Case 2? ("No" is a perfectly sound answer. I know I pry too much at times.)

I always imagined to have a perfect marriage. Like a typical committed marriage. And fantasies should remain as fantasies. But, if something spices up the marriage and makes it very erotic, then it can be achieved with moderation and frontiers.

So, if in case wife ever wants to have a "typical" hotwife lifestyle I am "always" ready to encourage her but with "little" sadness for turning away from my sentimental definition of marriage.

Honestly speaking, this sadness for me in itself could be an erotic trigger too..but as I always said, this is how it is as of now, things may change with time.
