I posted this on another forum as well, but didn't get many replies. So, I recently got an Oxballs pighole XL which is a really exciting toy. However, I've had bit of a problem with it. When I insert my my SquarePeg Toys Sigmund dildo or XL Egg plug the stretch feels absolutely incredible, but when I try to pull it out while keeping the pighole in my ass I experience a slight but sharp pain. I assume this is from a vacuum effect which effectively is trying to pull my intestines out of the pighole. Anyone who's experienced anything like this? Got any suggestions how to reduce the vacuum effect? Or, do you have any suggestions for other possibilities now that I have a pighole in my arsenal? I want to be creative with it!
