That being said, the Catholic Church was not frequently able or even willing to enforce such overly strict interpretations of the prohibition. It usually only enforced consanguinity laws when it wanted to apply political pressure on a secular lord seeking a marriage, and conversely, would often grant dispensation to a lord seeking to marry his third cousin if he was on good terms with the Church (. gave them generous land donations). By the thirteenth century, however, it was decided to finally update the official Church laws on incest to reflect the fact that they were using the new Germanic method of reckoning blood relatives: thus the Fourth Lateran Council of 1215 officially lowered the number of degrees in which marriage is forbidden from seven to four. This does not mean that long-held prohibitions on incest were suddenly relaxed, but rather that the laws and method of reckoning were finally brought closer back to their original alignment, forbidding marriage between what we would call "second cousins". Actually, the new rules in 1215 were slightly more strict in that two persons are related within four Germanic degrees of kinship if they share the same great-great-grandparents, which means that third cousins or closer were forbidden to marry (which was still far less than forbidding marriage between sixth cousins).
External irritants can sometimes cause a previously retractable prepuce to become non-retractable due to swelling of the tissues. If a child whose prepuce was retractable becomes non-retractable, environmental factors should be investigated. One known culprit is bubble bath. If a child is taking bubble baths and the prepuce becomes non-retractable, the bubble bath should be discontinued.
