Hi Buddy,
Sorry about the knee-jerk reaction, I'm sure you are very careful. I work in a med-related field and have lots of ER pals (city hospital) who tell me stories of retrieving lots of things that get "lost" in body cavities. The worst was a light bulb that broke in a guys ass. If you passed out while playing and a glass rod shattered up your cock... well, you know. I'm into a little erotic pain, but that would fall into the "permanent damage" category. The advantage of the sounds is that they are graduated in size and come in variety of shapes, but, I will say that torture with everyday items has it's own fetish appeal. If you are OK doing what you are doing, great. It's just that sometimes we don't think all that clearly when sex is on our minds.
