Reason: These first four imminent acts constitute imminent sex acts with 2 or more participants and, therefore, the imminent_sex tag. All of their non-imminent counterparts implicate sex.
The only counterargument I can think of is if sex is already ongoing and the character(s) are about to switch acts then the "sex" is no longer imminent, but about 1/5 of the imminent_sex posts are tagged sex and several of the subjects on the first page of imminent_sex sex are already engaged in sex acts. The other implications, aliases, and invalidation are descriptively self-evident and reflect the classification of the non imminent versions of the tags.
