To be fair, you can’t be infected with STI and don’t show STD symptoms. It takes time, like Few days or for HIV up to few years. The fact that it’s crazy, I agree. But consider this, we all know what cigarette smoking does to our body , but yet I smoke. It’s human’s normal thinking that bad things only happen to others, not me.
Meanwhile I guess as I mentioned before, CDC should take “unprotected sex with an stranger/sex worker” off the STI transmission protocol and add something like reading book or drinking coffee in public library, instead.
Either there are tons of sick guys who don’t come forward or they don’t go to Public library.
