This is not true for the people in arranged marriages that I’ve discussed the issue with. The men had not been sexually naive before the marriage. Women explained it as finally being able express affection so it was like a dam bursting into one person. They felt that sex was a critical ingredient to the marriage. Granted that has only been a handful of cases where that frank discussion took place, and it is only with a single cultural group, so you may have more extensive experience.
