The bulk update request #7427 is pending approval.

create implication planet_insertion (72) -> planet (4598)
create implication planet_insertion (72) -> object_insertion (854)
create implication planet_in_anus (38) -> planet_insertion (72)
create implication planet_in_anus (38) -> object_in_ass (31655)
create implication planet_in_pussy (26) -> planet_insertion (72)
create implication planet_in_pussy (26) -> object_in_pussy (819)

Reason: I can't see a case where these tags would not imply each other.

Wait, what is the purpose of object insertion? It seems to be equivalent to object penetration but the object isn't a sex toy, according to its wiki

Edit:
Ah, object penetration seems to be the union of object insertion and sex toy insertion. If there's value in this umbrella tag, it should be equipped with implications.

It's getting really tangential now, but I don't particularly like *_penetration, since it could refer to penetrating_* or *_penetrating (the character). (So in this case object_penetration could be interpreted as penetrating_object or object_penetrating
