Here’s my completely personal and subjective take on this question, Hailz.
Coming as I do from an earlier generation, one that had never even heard of safe sex, I’ve spent the past 45 years regularly practising unprotected, mostly but not exclusively, penetrative sex with my (male) partner, Given birth, and breastfed children. Yet none of them became infected. None of them even have antibodies.

This despite close living, in which each person in my family somewhere along the way would have say, used my toothbrush, or my facecloth. Certainly I know body fluids got swapped one way or another. So my advice is use condoms or whatever, and maybe do nothing too crazy, but as my grandma used to say “practice makes perfect”
