Chapter 156 – Perception of Blood as a Result of Cohabitation
156.1) If a woman bleeds due to cohabitation, she may have intercourse again after purifying herself.
156.2) She should examine herself after a second time of intercourse to ascertain that the flow is from the cohabitation and not a menstrual time.
156.3) If a woman thinks she has become unclean during cohabitation, she should inform her husband, he should continue until his organ relaxes, and consult a rabbi regarding the proper penance.
