Amazon has _Sex, Marriage, and Family Life in John Calvin's Geneva: Courtship, Engagement, and Marriage_. This 544-page tome is only _$1.99_ right now, a 96% markdown from the regular price of $46.50!
It's volume 1 of Eerdmans' "Religion, Marriage and Family Series."
There are not really enough ratings for it to meet my posting standards. But, it's a solid 4.00, from 11 ratings, by the GoodReads folks, and 5.00, from 2 ratings, from our Amazonian friends.
This is one that I'm, personally, going to pass on, however. It's not that I'm against sex, marriage, or family life. Or that I'm not interested in John Calvin or about what was going on in Geneva when the native Frenchman was there. And, I'm generally "into" religious books. It's just that I'm not interested in such a narrowly-focused topic. _You_ might be, especially at such a super price!
