It seems like you don't like the answers you've been given by us and you already had made your mind up. Why come here and ask? And, of course you don't go on to never having unprotected sex. But, there's a difference between casual, new and establish relationships.
On the contrary, I came here to seek some advice, but based on the advice provided, it seems the risks are low.
The key risks, HPV and herpes are extremely common (far more so than I'd realised before starting the thread) with significant proportions of the adult population carrying them without issue. It seems they are just as likely to be in your ONS as they are in your partner of 10 years. Also, they aren't tested for, which says a lot!
It seems analogous to Covid. Yes, no one wants Covid, and Covid can cause serious complications in a few cases, but I don't live my life in a mask or socially distancing. I recognise the risk with Covid, and have decided to accept it, as the vast majority of people now have. It seems similar with oral sex.
Promoting dental dams seem to be very similar to promoting masks for Covid.
