About 12 years ago I was scratched internally by a pushy, lazy, novice top. Unbeknown to me his nails were longer than expected, dirty and his hands unwashed. When he scratched me accidently, he introduced all the bacteria into me internally. This setup a massive infection which, I thought I was just coming down with the flu when I got sick.
After 48 hours I was seriously ill and was rushed to the ER. I had no idea why I was so sick. After 24 hours in the ER they discovered I was septic and getting sicker by the hour. I was starting to have severe abdominal pain and turned extremely pale. They placed me on 4 IV antibiotics, pain meds, anti-nausea meds, and other iv fluids. I was hospitalized for a week. Once I was getting better and the internal infection was slowing, they did a colonoscopy and discovered the top had over stretched my rectal cavity (lower portion) and damaged the inside walls by pushing too hard to fast. It was not a tear by very close to being a tear. After 10 days, I was discharged with bags and bags of antibiotics and nausea meds.
After 6 month my color returned, and I was able to enjoy the simple things in life like food. I learned from this experience if playing with a virgin top have another top there to help train them. Inspect their hands and ask a million questions. If you get a bad feeling leave or stop the session. There is lots of material out on the web on how to fist safely. If a novice is not willing to learn and read, they are reckless and could injure or end up killing you. Fisting is the most intense and intimate sexual experience a person can have. It is something that should never be rushed or done by a lazy useless uncaring fucker.
