If you were ever in the Army and deployed overseas, you already have every shot for every disease that ever existed or will exist and you will never ever get sick from anything for all of eternity. Even when they dig up your corpse from your gave 5000 years from now, your body will be 100% intact, because even the bacteria that would normally feed on your body will go look someplace else.
But seriously, don't be an idiot, and it oughtn't to be a problem. Pick up a streetwalker then DATYO her? Yea, you're going to die before dinner time. Visit a lady who has 10000 reviews a week on here and you take a sniff and it smells a little? Yea, you may need penicillin. But look, sniff and lick, check your surroundings, then get in there. Have a regular test, and wear cover or use listerine or the rubbing alcohol wipes or whatever gets you through the day. I'm in my fourth decade of this hobby, and the worst I ever got was COVID once in Sochi. Be safe and smart, shouldn't be a problem. If you are ascared or germophobe, this hobby is 100% no for you. Remember, when you slide in there, there was another cock in there ten minutes ago, and not just that, but she may like him more than she likes you, and he barebacked her and creampied her.
