Uhhh, helloo there, YES you definitely can perforate your colon with a vegetable. You can perforate a colon with a broom stick for goodness sake.
Get yourself checked... docs see it all, no need to be embarrassed. Its better to be embarrassed in front of a private doctor than a squad at your local ER.
Alot of us experiment, with lots of different things. To each their own, let no one judge you over it. (not that , that was a concern)
Ive also unfortunately come across MOSTLY all negative or snide remarks, coming from the one who 'thought' you cant perforate a colon with a vegetable. And may I ask that particular poster..........do you normally have 'mucus' come from your anal area accompanied by severe lower abdomen pain????? I dont.
