An Erectum is when the man inserts his penis into his partner's ass before it is erect, and then it becomes erect while sitting inside of their partner's ass.

Erectum

When you have to poop so badly that your rectum feels hard. It is often harder to get all the poop out when you go since it is dense and very hard.

"I need to poop so bad. I have an erectum."
