Always bare with regular lovers. Except if I have a bad impression, it is up to random lovers I meet during business trips or holidays to use condoms or not. But most of the time they prefer to go bare or even don't ask. I feel to be a real woman when I feel a bare cock inside me and then feel the warm sperm of my lover invading my pussy. Then I got tested regularly and so far never had to face major issue. And as I am lucky to have a very regular cycle, I managed to never get pregnant despite no being on BC.
