Steve, please answer the question, why should we "celelebrate"
sexual behaviour which produces such results?

Apparently sexual custom in parts of Africa determines that hetero males behave in a very promiscuous manner, this is to be condemned, but at the moment we are discussing infection rates in the developed western countries where information and education is readily available.    Perhaps you could take a little time out from your "celebrations" to explain the huge discrepancies between homo and hetero infection rates, not only for hiv but for most serious, sexually transmitted diseases.
