There is no truth to the story that a Memphis man named "John" contracted AIDS from having unprotected sex with a sex doll during his bachelor party along with several of his friends while using drugs and alcohol. He also didn't infect his wife the next day after the marriage went through.
The origin of the story is the highly controversial site WitTheShit who published the original article (archived here) under the title "3 men contracted Aids from running a train on a sex doll". The article opened:
This story comes from a Memphis man, it was told that he was about to get married and he told his fiancée he was going to have a bachelor party. She didnt like the idea because she didnt want him with any strippers. So thinking outside of the box, 3 of his friends ordered a sex doll online for the bachelor party.
The fact that the story appeared in a category named "Extreme Horror Humor" should be a dead giveaway about the veracity of the article.

Their greatest 'hit' so far was a story about a rapper who was arrested for murder after revealing he did it in a rap song. They also invented other stories about sexual harrasment and drugs in the past, so anything they publish should be taken with a big grain of salt.
