re: Married couples with an "arrangement"

Yeah we used to be 3-4 times a week.

We moved, kids changed schools, changed sports leagues (which city), changed jobs, started daycare, wife went back to work.

It slowed down to 4-5 a month. Wife is aware of it, I make sure to do my part and help out with kids, laundry, household tasks, flirt with her even though I know it's not going down.

Life ebs and flows, don't be bitter at your partner when there is a slow down.
