I just feel like eventually the "more and more" hits a limit right?

I'm imagining a couple that fucks "more and more" everyday. The first day they fuck once. Then the next it's twice. Three times on the third day.

After a year you are fucking 365 times a day. Even with people only lasting 3 minutes, that's 1095 minutes per day or about 18.25 hours a day of fucking.

At some point the more and more everyday has to turn into "the same amount every day" right?
