Here’s something unexpected to look forward to when your marriage hits the 50 year milestone. For many, if not most couples who have been together for a long time, things can get a little dull in the bedroom. Now a study says that after around 50 years of marriage, your sex life could pick up again thanks to a renewed sense of trust and commitment.

Researchers at Louisiana State university analyzed the sex lives of over 1,600 adults from their late-50s all the way to their mid-80s. They noticed a slight "rebound" in how often long-married couples were having sex once they had surpassed 50 years of marriage.

They say that while new couples start off with vibrant sex lives, the frequency often diminishes over time. But the good news for long-married couples is that after all those years together, a sense of commitment, and continuity could be what leads to an uptick in sexual activity

Another fascinating finding was the frequency of sex in first marriages versus second marriages. Researchers found that people who stay in their first marriages instead of getting divorced and remarried, often have more sex.
