Want more sex? Get married and wait 50 years!

For all of you who think sex between elderly folks happens about as often as Halley’s Comet—think again. Turns out, couples experience a rebound in sexual activity after 50 years of marriage, according to a study published in the journal Archives of Sexual Behavior.

Researchers from Louisiana State University, Florida State University, and Baylor University analyzed data from 1,656 married couples ages 57 to 85. And while they didn’t find too many couples who survived into their fifth decade of marriage, the ones they did find saw a small rise in sexual activity after the half-century mark.

What could possibly be the motivating factor behind this bump? Researchers say: trust. “You may have a higher level of trust when you feel that your spouse isn’t going to go anywhere,” suggested Samuel Stroope, assistant professor of sociology said at LSU. “The expectation that the relationship will continue may give you more reason to invest in the relationship—including in sexual aspects of the relationship.”

Because nothing lets you know you can really rely on your life partner than 50 years of relying on your life partner. Stroope also attributed the rise to older folks being more even-keeled, “which may help cut down on marital conflict and facilitate regular sexual activity into advanced age.”

The researchers also found that people who were remarried had sex less frequently than those still in their first marriage—which researchers speculate could involve a weaker sense of “permanence or lasting investment.”

Now, if you would excuse me, I need to find a husband stat so that when I’m in my mid-70s I can live it up.
