Eggs, that's interesting. Eggs are pretty full of symbolism ;). I'm not into food insertion, myself, and like you mentioned, it hasn't seemed very common in sissy spaces I've been. Around puberty, I did use personal household objects for anal play. I can't remember when I got my first dildo right now. I think during my household object play era, I might've had some difficulty (that I completely resolved on own) with getting an object back out -- it just took a while. I think that probably scared me permanently off of using anything without a flared base. Enjoy yourself and play safe!
Yeah I had a similar experience and couldn’t get the object out. Hid it from my parents for 3 days and was not doing well. Couldn’t eat and turned out internal bleeding and had I not gone to the hospital - sepsis.
I still love anal play but when I see videos of people putting jumbo sized cans up their butts, I freak out and can’t watch. Your body is a vacuum and will suck something like a can or other objects in and out of reach.
Genuine Curiosity: what happens when an egg breaks?
I get the slimy part, but how dangerous are the shell fragments?
I'm not a nurse or doctor, but I'd guess they're about as dangerous as anal play could get - which includes life-threatening. Shell fragments are strong and quite sharp in a body area not at all designed for physical protection. The cost of a cut inside you is the contents of your colon getting into your blood and abdominal cavity. And if you need to go to the hospital, you're probably getting surgery. Super yikes!
