I'm just wondering if the science has kept up with the changes in which sexual activity takes place. Knowing about the transmission of HIV and AIDS today and the many risk factors involved--multiple partners and unprotected sex--has the science kept pace? Are you referring to recent scientific studies that reflect this? Why not simply include multiple partners and unprotected sex as exclusionary criteria in a list? If that's the best way to describe the risk involved, why not just do that?
