However even if at that time women are as vulnerable to falling into lust as men it is only for 2 or 3 days in 26-30.
I agree, that's why I previously stated that zone of being the most prone to sins of impurity is about 2-5 days before their menstruation, but maybe it's a little earlier, and it lasts about 2-3 days.
Also, during that 2-3 day zone, the probability of married women cheating on their husbands is higher, albeit, even if the probability is still very low, but it depends on the woman.
Many stupid husbands aren't in tune with their wives. They better watch them, if the husbands even care...
