Not my personal experiences but a few things I have seen in the ER:
- A guy that parked his motorcycle right next to ER door, and hobbled in looking very uncomfortable. He had lost a large dildo up his ass and couldn't get it out. It had been there a few days and he had to go down for surgery for removal. On his rounds to check with the patient the next day the surgeon handed him a plastic bag containing the dildo and said "I believe this is yours"
- A young couple who had used a light bulb as a dildo. It exploded inside her causing numerous cuts and a heavy loss of *******.
- A guy that removed the hose from a vacuum and inserted his dick in the opening. Unfortunately for him there was a metal fan about five inches inside the opening and his dick was probably 5.5 inches before the modification.
Those are three that stand out but I saw and heard of dozens of sexually related injuries in my time in the ER.
