concern redirects bloodflow very fast. speaking from experience, i had a partner slip and fall mid-intercourse. Your brain decides for your body pretty quick what the priority is.
Unless you're a serious sadist who actually gets off on that. I have a friend who's a sadist in a committed relationship, and once when things accidentally went a bit too far (no lasting damage) he, in his own words, 'went from 60 to 0 in under two seconds'
