I had a regular BFE guy in NY I flew regularly and we had overnights constantly, probably made 45k last year easily tell me he wanted to start wearing condoms in our bookings. I was confused as I had all my vaccines/prep/doxy and haven't had an STI in 2 years and I asked him if it was something temporary (maybe he was clearing something) but he said no. I told him that wasn't going to work for me, to reach out if things ever changed and wished him the best.
We all set up boundaries in our interactions and it's on us to respect each other's and walk away when they're a mismatch.
Oh and with my regulars we have a set rate, what changes is the time I book with them and that's kept them from raising them on me at least. They know I tend to book multiple hours so they're OK with keeping the rate and get a longer booking.
