But you want things to soak into the wood
That's the anti-bacterial property of wood - bacteria are pulled into it and die of dehydration. I've never oiled my wooden boards either. I have one large one that lives on my counter and I do most of my prep there; I do veg first, then cut meat, then clean it, usually with a spritz of homemade all-purpose cleaner made with 1/3 white vinegar, 1/3 lemon juice and 1/3 water. No problems whatsoever.
btw, here's a link to the research done on cutting board materials:
