Personally, I have always followed the protocol of urinating right after sex followed by a long soapy shower. I also gargle Listerine right after any oral sex (including rimming). To date, after 1000+ partners, I have only had oral gonorrhea once. And that happened shortly after a meet up that I fell asleep right after and didn't follow my own protocol. Perhaps I'm lucky, or it actually works. It has done well for me. I am now on PrEP and play mostly safe, but I'm sure something will come along at some point. And I do get tested every three months or sooner if I feel I've been exposed or have a symptom. While not afraid of contracting most STI's, I would feel bad if I passed it along to someone else.
