Help please! is getting a naval piercing at a semi shady place probable cause to get tested for aids/hiv?

Possibly, depends...: Hiv transmission can occur in more obscure ways, such as piercings and tattoos. Most of these transmissions have been reported more in the jail or prison setting, where there may be higher rates of sharing needles or tools used for piercings or tattoos. Just make sure that wherever you go for your piercing, that they use unused or cleaned instruments.
