Kris Humphries wasn't the only person who wanted to consummate his marriage to Kim Kardashian this weekend, 'cause at the same time ... MILLIONS of "fans" were flooding the official website for Kim's XXX tape.

TMZ has learned ... roughly 2 MILLION people visited KimKsuperstar.com between Friday and Sunday night ... a HUGE boost from the average weekend traffic.

In fact, the site only averages 300k unique visitors PER MONTH -- so it seems all the fanfare from the wedding led to some serious handfare across the planet.

And get this laddies -- according to Google Trends, America did NOT lead the pack in Internet searches for "Kim Kardashian Sex Tape" ... that honor went to Ireland.
