That poor human. From memory the snake entering and leaving causes pain so unless they are into pain play....

Thanks for that image..... But i was always kind of hazy about the whole process. My best understanding is that upon reaching puberty the imune system of a jaffa shuts down. Then the pouch is cut and the symbiont implanted who keeps the imune system going and keeps the pouch open. If tretonin was used instead there would be no need to cut pouches.
