One of the most compelling arguments against the existence of God is the fact that so many fun things are bad for you, and so many boring things are good for you.
What kind of sick creator would make drinking, smoking and cheesecake bad for you, but early nights, jogging and celery good for you?
Well, don't abandon all faith in the big man in the sky just yet, 'cause it seems regular ejaculation is in the healthy column.
Researchers at Harvard University found that men who ejaculate at least 21 times a month could see their chances of getting prostate cancer slashed by a third.
The study - which was published in European Urology in 2016 - involved 31,925 men, who filled out three questionnaires about ejaculation frequency between 1992 and 2010.
The results indicated a statistically significant reduction in prostate cancer rates among men who ejaculated frequently.
The study said: "We evaluated whether ejaculation frequency throughout adulthood is related to prostate cancer risk in a large US-based study.
"We found that men reporting higher compared to lower ejaculatory frequency in adulthood were less likely to be subsequently diagnosed with prostate cancer.
"These findings provide additional evidence of a beneficial role of more frequent ejaculation throughout adult life in the etiology of PCa [prostate cancer], particularly for low-risk disease."
So there you have it fellas - doctor's orders.
This isn't the first study to link masturbation and reduced risk of cancer, either.
All the way back in 2003, researchers in Australia questioned more than 1,000 men with prostate cancer and 1,250 without about their sexual habits.
They found that those who had ejaculated the most between the ages of 20 and 50 were least likely to develop cancer.
Graham Giles, of the Cancer Council Victoria in Melbourne - who led the research team - told New Scientist: "It's a prostatic stagnation hypothesis. The more you flush the ducts out, the less there is to hang around and damage the cells that line them."

Studies thus far have only been able to prove a connection between increased ejaculation and lowered risk of prostate cancer.
But still, while we may not yet have an explanation, it's a correlation many of us will be happy to get on board with.
