Pretty interesting findings out of Sweden:
Some HIV-negative men in long term relationships with HIV-positive men have an antibody response in saliva which may inhibit HIV infection, report Swedish researchers in an article published online ahead of print in AIDS. This is the first time that such a response has been described in saliva, and may help explain why infection through oral sex is somewhat infrequently reported even in serodiscordant couples.
While it is well established that while HIV infection during fellatio and other types of oral sex can and does happen, the number of infections that can be attributed to oral sex is relatively small in comparison with the number of times that unprotected oral sex is practiced. One reason is that saliva contains enzymes which partially inhibit HIV infection.
Neato! The new safer sex message: Suck, swallow, repeat!
I heart your new safer sex message, I feel as if advertised well it can really get some traction, Trevor.
It's an interesting find no doubt, kind of put some science behind what was already a common assumption/known fact.
Also the image you posted gives a new perspective of "chokes on dick".
i like the xray pic of the blow job. you have an xray of two men fucking cock in ass xray ?
I'm just thinking how lucky that cocksucker is!
...And the cocksman prolly doesn't get it that good, very often, either.
