object insertion
When an inanimate object, such as a vibrator, dildo, a carrot, etc., is inserted either vaginally or anally.
This does not apply to a penis being inserted; use the sex tag for that. It also does not apply to other body parts, such as fingers or tentacles. For tentacles, use tentacle sex.
