My latest article corrects fallacies about the workload of the medieval peasant and serf. It demonstrates that despite modern myths, they worked far fewer hours at a more plausible rate than we do!

Quote

One thing the Middle Ages had plenty of time for was my favorite pastime – sex. Multiple studies indicate married and "religious" couples (more common during the Middle Ages) especially have the most satisfying sex and more of it. 
For all our focus on sex, it seems our increasingly secular world is having less of it. Each decade we have less and less, sex. Pornography and other influences affect the frequency, but work hours and fatigue also play a role. Due to our overworking and hectic lifestyle, people are exhausted and worn out, lacking time for lovemaking or love in general.
As our secular world increasingly replaces love, romance, and happiness with labor and materialism, I can only predict the trends will continue. 
Coupled with fewer marriages and, therefore, less frequent, meaningful, and satisfying sex, it seems it will be up to the Church to "make sex great again" because modern life is destroying it.

Interesting read. I look forward to more of your work. God bless.
