how many people are cumming at any given moment?

lets say that there are 8 billion people, a conservative 1 orgasm per day. 60 * 24 hours in a day, so 8,000,000,000/(60 * 24) = 5 555 555.56 orgasms per minute and therefore 92,592.59 per second.

because the average duration of a male orgasm is ~6 seconds and ~12 for females, the duration of an average orgasm will be assumed as 9 seconds. 92,592.59 * 9 = 833,333.31 people that could be cumming simultaneously.
