Answer:
The answer is The woman leaves her partner and ruins his reputation.
Step-by-step explanation:
In the life of all married people, it is the expectation of all women that they would be satisfied by their husband. Since the culture of Kayla recognised this by virtue of being a decendant of Mangaia, she would definitely expect her husband to leave up to expectation in being satisfied sexually.
If this did not happen, she would leave her partner as a consequence of her unfulfilment. This would lead to the running of the reputation of her partner because people would start to assume that he has an existing medical condition hence the reason why his wife left him.
