. In my opinion giving Vulcanians human mating drives is an example of small universe syndrome, becasue we can't imagine abstaining for seven years.
T'Pol, banged Trip, 7 year mating cycle had nothing to do with that. And you cannot ignore Amanda, she is married to a Vulcan and seems pretty happy about it, so either she is non sexual or has a non Vulcan partner to scratch her itch or her husband sexually satisfies his human wife orally or otherwise.
