I've never personally known a single hetero male who's contracted HIV via tradional vaginal sex. Blood and semen are where the HIV virus is concentrared - not vaginal fluids. This explains why women are at a higher risk of contraction than men. And why homosexuals and those who share syringes are the highest. Moreover, this also explains why HIV is rampant in black community - many, many black men are secretly gay AKA on the down-low.
