About metzitza bpeh, mohelim in my circles generally use a pipette. But they do it to protect themselves.
I don’t really know if there is any danger to metzitza bpeh. All I know is we did it for thousands of years, and it was certainly what G-d wanted us to be doing then. Perhaps now there are more diseases, or whatever. But I am leery about thinking of it as an arcane uncivilized practice.
