As part of a larger $12 million HIV study by UCLA researchers, a grant using $823,200 in federal stimulus money was spent on examining "the feasibility and acceptability of a post-coital male genital hygiene procedure, which participants will be asked to practice immediately post-coitus or at least 12 hours after" among uncircumsized men in Orange Farm, South Africa.

The genital-washing portion of the experiment will be completed in 2011, after which another study will be launched to discover whether or not the "penile cleansing procedure" works to prevent HIV transmission.

“If we find that men are able to practice consistent washing practices after sex, we will plan to test whether this might protect men from becoming HIV infected in a later study,” the grant says.

Your tax dollars are being used to teach dudes how to wash their dicks...lovely.
