Was Spock's Pon Farr in Amok Time his first time experiencing it? The events in Amok Time seem to indicate it was Spock's first time experiencing it, especially if we consider Vulcans to be monogamous. We are told that Vulcan's go through it every seven years of their adult life. So does Vulcan adulthood begin at age 36(Spock's age in Amok Time)? In the Search for Spock he goes through Pon Farr with Saavik. The Spock that does this is credited as "Spock...Age 17". This could indicate that adulthood begins much earlier. If we take Spock's age in Amok Time and start subtracting 7 years we get: 36 -7 = 29 29 - 7 = 22 22 - 7 = 15 That means Spock went through Pon Farr at the ages of 36, 29, 22, and 15. That's three times, prior to Amok Time. I think this is actually the most likely. But then what happens to Spock and T'pring and their less than a marriage and more than a betrothal?
