The type of bodily fluid involved as well as the number of sexual partners you have determines the extent of risk involved in sexual practices.

Since the highest concentration of the HI-virus is found in blood, semen, pre-cum and vaginal secretions, sexual activities involving these bodily fluids are more risky than contact with saliva, tears, urine and sweat, that have low concentrations of the HI-virus.

Obviously the risk will increase with the numbers of partners you have who are, or have been, involved in unprotected sexual practices.
