The other day on the radio they were talking about this topic. I had to look on the internet to see if this phenomenon actually exists. What are bug parties? Bug parties are sex parties often ranging from a few to as much as 30 people. Unsafe sex with every participant at the party is encouraged. There are several variations of bug parties. At some, there is one member of the "orgy" that is HIV positive. Only this individual and the host know his positive status. The remaining participants know that there is an infected person in the room, but do not know his identity. The participants then partake in a night usually filled with alcohol, drugs and of course unsafe sex. In other variations of a bug party, there is one person who is not infected with HIV, however the other participants are or may be. Every one is aware of the person who disease free. The HIV negative person then allows the infected guys to have unprotected anal sex with him. What is a "bug chaser?" A bug chaser is a gay man who deliberately attempts to contract HIV by having unprotected sex with a man or group of men who are known to have the virus.
