People watch more porn in winter and early summer as study of XXX Google search
 

One theory is that it is because these times coincide with the main holiday season in most western countries, when people's minds turn to leisure activities rather than work.
Researchers at Villanova University in Pennsylvania plugged 'porn', 'xxx' and x-rated' into Google Trends as well as a range of more specific naughty words and phrases.

Fucking amazing. The sun shines and people go outside to play.

Does NASA know this? LOL
