Just cover it up and pray.
Condoms are supposed to protect against most STIs. HPV and other contact STIs are like 2% chance of getting it from oral or something.
Not sure about that, you might want to read this:
"Around 1 in 4 mouth cancers and 1 in 3 throat cancers are HPV-related, but in younger patients most throat cancers are now HPV-related."

Covered intercourse is, undoubtedly, much safe than uncovered oral sex. Since I am mostly an uncovered mutual oral sex guy for most of my career the last 20 plus years also including girlfriends outside paid sex, I am guessing it's likely I have HPV and also probable that I am at risk for such cancers. I worry if I start coughing for no apparent reason or feel something off in my throat.
