based on this
http://www.internetworldstats.com/stats.htmwe have about 2.8 billion people with the internet. the ratio is anywhere from 1:1 to 1.06:1 in favor of men, so let's say 1.4 billion of these people are men. about 65% of the world population is 15-64*, so it stands to reason that about 900 million men have heard about this news. I am ignoring issues of timezones here cuz this shit is universal. flabby and sick dudes in croatia are being woken up for this shit. Also, IIRC about 10% of the population is gay, so let's cut it down to about 800 million dudes who care about this shit. let's say for argument that the average guy has masturbated once to these images
so far, with some masturbating zero times and some masturbating dozens (no names). apparently the range of semen ejaculated is .1 to 10 ml, the typical being around 5ml (aka teaspoon). a teaspoon is 0.00130208 gallons, so we can probably estimate 1,041,664 gallons of semen have been outputted today.
*I am aware that 12 year olds are probably tuggin their little dicks constantly but the cum is 90% pee so we aren't gonna count that.
