No, the answer to AIDS is keeping it in your pants.
Keeping it out of somebody's butt would work well.
I am no Doctor , but I did stay at a Holiday Inn once, i guess that makes me as smart as Bubba.
I dont see why circumcision would help prevent aids unles the problem is that after anal sex the poop stays in under the foreskin. Maybe a good wash job after packing the fudge would work as well.
