CNN discusses a couple's experience with a new year's resolution to have sex at least once a day, and they integrate findings from numerous research studies that indicate benefits of frequent sex for women and men (longevity, cardiac health, lower blood pressure, lower breast and prostate cancer risk, analgesia, slimmer physique, improved testosterone management, reduction in menopause symptoms, and improved quality of semen).

...I did the math, and that's kind of a lot of sex, if only intercourse counts.
I guess, though if you are sexually active between, say, 16 and 66, then that comes out to sex on average once every six days. The sexual resolution couple would have to keep up their practice for January and another 98 months, or more than eight years.

CNN said:(CNN) -- Yoga instructor Sadie Nardini and her husband got an early start on their New Year's resolution: In December, the New York couple decided to have sex every day for the entire month.
Nardini and her husband, a professional photographer, initially decided to have sex like bunnies in the hopes that all the activity might help them overcome his-and-her bad habits: cigarettes and chocolate, respectively. And indeed, the nightly trysts did help. But they also found, unexpectedly, that frequent sex made them feel better in other ways, too.
Nardini says they both slept better and had more energy, and she didn't get a cold or the flu all month as she usually does in the winter. "Sex doesn't seem at first glance to be the cure for what ails you, but there's so many health benefits of having more sex," Nardini says. "Anyone can be better served by having more sex."
In fact, the experiment was so successful, the couple plans to have daily sex in January, too.
Researchers have long known that not only is sex fun (when done with the right person, of course), but that people who have frequent sex tend to live longer and have healthier hearts and lower rates of certain cancers. These studies also show that men with an active sex life have healthier sperm, and sexually active women have fewer menopause symptoms.

CNN said:A Minnesota study found that men who'd had intercourse more than 3,000 times in their lives had half the prostate cancer risk of those who had not. While it's not clear why this would be true, studies have found that men who had more intercourse tended to have better prostate function and eliminated more waste products in their semen. "These differences could conceivably impact prostate cancer risk," Brody writes in his article.
