the biologic response know as "pre-cum" is to prep the urethra and change it's acidic ph to alkaline so sperm is not damaged.
semen needs an alkaline environment to survive, acidic environments approach sterility---this is why blowing a load in someone's mouth is mostly safe unless, as others have indicated there is a sore open to bloodstream.
class dismissed.
