text: could someone receive hiv/aids if....? critical thinking questions from my science textbook:  ... if a male that has already gone through puberty were to where an older cousin's underwear(who is not infected with hiv/aids)  .... if a male that has already gone through puberty were to where a friend's underwear(that has already gone through puberty and is not infected with hiv/aids).  what i think is that since there is no hiv/aids in the first place, nothing is transmitted?  your help is appreciated, thank you aids/hiv is transmitted through the exchange of bodily fluids through the bloodstream.
