Nothing cures the agony of defeat like furious masturbation -- at least that's how Broncos Nation decided to deal with its grief last night ... after losing the Super Bowl 43-8.

XXX giant PornHub.com just released some fascinating stats from last night's porn viewership on its website -- showing overall viewership was down 32% during the big game ... down even more in Denver (51%) and Seattle (61%). Makes sense.

The tide turns around the halftime mark (EST) ... when most of the audience bailed on the game ... but things got even more interesting after the final score.

While porn viewing numbers in Seattle and Washington dropped below average in the wake of their massive victory -- presumably because everyone was out partying -- the numbers in Denver and Colorado surged to 10.8% and 7.6% above average, respectively.
