That's the phrase I use to describe it.
If you're not done with your share of sex when you get married, you are at risk of giving in to temptation when you're married. Mostly from a guy's point of view because a guy tends to have more opportunities when he gets older, but the same logic works for women to a degree.
One of my friends would get laid constantly in our 20s. Not just bragging about it, he provably had the gift for it when we were out. He was banging chicks constantly, to the point where he had to phone me from work to stop his various chicks from finding out about each other. I thought for sure this guy would not be able to hold out in a marriage.
15 years on and he hasn't cheated on his wife, that last of this parade of women.
My boss married his high school sweetheart. He started going to a lot of meetings with a broker. I was joking that he was having an affair. Turned out to be exactly what happened.
My other boss also got married early. Religious guy, 5 kids. I go to see him a decade after we last worked together, what does he do? He wants me to wingman him. Also shows me all his messages from various women. (He's also in politics, so maybe it's par for the course.)
Sex is pretty powerful by nature, but like many things evolution has left us, there's a point where our curiosity is satisfied. We can move on with forming relationships when the urge is not quite so strong.
