No, he's just a big pervert with a loud mouth. He's come up with some pretty sick shit over the years but this was by far the sickest.
He mentioned something about seeing a story on TV about guys called "bug chasers" which were gay guys trying to get infected so they didn't have to worry about it. I'm thinking that plus the alcohol lead to his "idea."
The part that scares me though is that in some parts of the world where human life has no value I could see this happening. Think about it...there's parts of Africa where people believe you can be cured of AIDS if you have sex with a virgin.
