How long does it take for bodily fluids such as sperm/vaginal fluid containing an std to dry out when on a vibrator and placed in a dark, cool drawer? how long till an std like syphillis is dead when exposed to the air?

These STD'S viruses can survive for several days outside the body, but dry up and become inactive. Sperm and vaginal fluids dry up the fastest, in a number of hours. The HIV can survive in a syringe, in cool temperatures, and at a PH around 7.This is only for a few days. There has to be blood to blood transmission for a positive result. Always clean and sterilize sex toys.

Most bacteria and viruses die within a few hrs. some like hepc, b might take longer
