A recent NSFW Reddit thread asked “Doctors/nurses of reddit, what’s the most embarrassing sex-related injury you’ve treated?” It seems many people are happy to dig around the house looking for things they can use as makeshift toys in the bedroom and while that may seem adventurous, it can also be dangerous and a lot of folks end up in the ER.

As you can imagine, most of the stories sound really painful and involve unspeakable things, so we’ll just share some of the most common things people use during sex that lead to injuries. British escort agency Xstasy did the research and according to their data, these are the top offenders:

• Computer chair
• Bowling pin
• Lava lamp
• Toilet brush
• Jalapeños
• Bicycle pump
• Shower head
• Candle stick
• Candy bar

Experts warn not to try these at home. And it’s solid advice because you don’t want to end up on some Reddit thread about sex-related injuries.
