CarolC: I'm afraid you haven't understood what's going on here medically. You absolutely do not get HIV by having sex with mutiple partners. You get it on the occasion you have sex with one partner, who is infected himself/herself. and they transmit the infection to you. You may then, of course, pass it on if you go on to have sex with someone else. But when you get it, you get it from sex with one partner. If you use a condom on that occasion you reduce the risk. Likewise, this modern research is suggesting you may reduce the risk if you are circumcised. It is not at all irresponsible to do this kind of research, or to publicise and discuss the results. It would, of course, be grossly irresponsible to recommend getting circumcised as a reliable means of avoiding getting, or passing on, any sexually transmitted disease: because it's not very effective!.
