Kidney stones, or avoidance of, are a good reason to drink lots of water and keep those kidneys flushed out.
Dallas was bad about bareback some years ago, maybe 10 or more. There were threads on the AR forum talking about it. I had a couple of condoms break over the years, and I didn't even know until I saw it with my eyes. Luckily, I always saw it before squirting. Some say they get more feeling bare, and it does depend on the condom. Is that little bit of extra feeling really worth taking a chance? Not to me.
