My understanding. The body's mucous membranes are equipped with their own sophisticated mechanisms for protecting your body from invasion by pathogens.
When you use mouthwash after giving a bj or try to douche your ass after getting fucked without a condom (or if the condom breaks), you are doing more harm than good by washing away your body's natural defenses.
Besides, if spunk is already in your mouth or ass, it's too late to be trying to wash it away. Might as well just savor it. I know Cupidman will agree
