What is your worst sex experience

My worst sex experience: So me and my partner were having sex, doggy style position. My partner was going at medium speed and his Penis slipped out and partially went into my butt. At the speed of lightning my butt cheeks locked up and my body went stiff. It felt like I had to pass out because of all the pain I was in. I could not finish having sex and my butt was sore for a week.
