This thread reminds me of a post someone made years ago about Orthodox Jewish rabbis who have seriously discussed, for hours on end, about penile penetration of a woman during her period (which is a sin) via an accident, and whether God would forgive, etc. IIRC, one example the rabbis went round and round on was, if you fell out of an open window sporting a boner and accidentally landed on a menstruating woman sunbathing in the nude down below and penetrated her on contact, would you be guilty of sin?
